Crochet Essentials: A Best Complete 20 Skills and Abbreviations Guide

This complete crochet guide follows a visual-first structure: study each original image, then read the matching skill and instructions immediately underneath. It covers hook selection, yarn control, slip knots, chains, fundamental stitches, rows, rings, conversions, and the full abbreviation list shown in the supplied reference.

Terminology: The teaching sections use US terms. The conversion table near the end explains the UK equivalents.

Crochet hook and yarn reference

Hook labels vary between the UK, metric, and US systems. Use the metric measurement as the main reference when two labels appear to conflict, and compare it with the recommendation printed on the yarn label or specified in your pattern.

UK Metric US
14 2 mm
13 2.25 mm B/1
12 2.5 mm
2.75 mm C/2
11 3 mm
10 3.25 mm D/3

Which hook should I use?

Hook size Typical UK yarn weight
2.5–3.5 mm 4-ply / fine yarn
3.5–4.5 mm DK / light worsted yarn
5–6 mm Aran / worsted yarn
7 mm and larger Chunky / bulky yarn

These are starting ranges rather than strict rules. Use a smaller hook for dense amigurumi fabric, or a larger hook when a project needs more drape. Make a gauge swatch for garments, fitted accessories, and any project where finished dimensions matter.

Holding the hook and yarn

Each photograph is separate. Read the complete method directly below it before trying the next position.

Pencil grip for holding a crochet hook

Skill 1A

Pencil method

Hold the crochet hook as if writing with a pencil. Rest the grip between the thumb and index finger, about 3–5 cm from the hooked end. Keep the remaining fingers relaxed. This position supports small, precise movements and can give excellent control for delicate stitches.

Knife grip for holding a crochet hook - crochet essentials

Skill 1B

Knife method

Hold the hook from above like a table knife, with the handle resting lightly against the palm. Place the thumb and index finger near the grip and allow the wrist to guide the movement. Do not squeeze. The pencil and knife grips are equally valid; use the one that feels natural and pain-free.

First crochet yarn tension method

Skill 2A

Yarn tension: method one

Pass the yarn between the little finger and ring finger of the non-hook hand. Carry it behind the middle fingers, then over the index finger. Pinch the work between the thumb and middle finger. The index finger guides the yarn while the lower fingers create gentle resistance.

Second crochet yarn tension method

Skill 2B

Yarn tension: method two

Loop the yarn loosely around the little finger, pass it behind the middle and ring fingers, and bring it over the index finger. This adds more resistance than method one. Adjust or remove a wrap if the yarn stops feeding smoothly. Even tension comes from repeatable movement, not tight pulling.

Making a slip knot and foundation chain

Follow the photographs from left to right. Every photograph has its own instruction immediately underneath.

Slip knot step 1: Hold the yarn tail

Slip knot · Step 1

Hold the yarn tail

Hold the tail in the non-hook hand. Cross the working yarn over it to form a loose circular loop. Keep the crossing point visible between the thumb and index finger.

Slip knot step 2: Insert the hook

Slip knot · Step 2

Insert the hook

Hold the loop securely and insert the crochet hook through the center from front to back. Keep the loop open so the hook does not catch the wrong strand.

Slip knot step 3: Catch the working yarn

Slip knot · Step 3

Catch the working yarn

Use the hook to catch the working yarn and pull it back through the center of the loop. The new loop on the hook becomes the adjustable working loop.

Slip knot step 4: Tighten the slip knot

Slip knot · Step 4

Tighten the slip knot

Pull the yarn tail and working strand to close the knot. Then pull only the working yarn until the loop sits close to the hook without touching it tightly. The loop must still slide.

Foundation chain step 1: Position the yarn

Chain stitch · Step 1

Position the yarn

Hold the hook in the dominant hand and the yarn in the other hand. Pinch the slip knot below the hook. Move the hook under and over the working yarn so the yarn rests in the hook groove.

Foundation chain step 2: Pull through the loop

Chain stitch · Step 2

Pull through the loop

Rotate the hook slightly downward and draw the yarn through the slip-knot loop. This completes the first chain stitch and leaves one working loop on the hook.

Foundation chain step 3: Repeat the chain motion

Chain stitch · Step 3

Repeat the chain motion

Yarn over and pull through the working loop again. Repeat the same smooth movement without tightening after every stitch. Similar movements create even V-shaped links.

Foundation chain step 4: Check the chain length

Chain stitch · Step 4

Check the chain length

Continue until the chain contains the number required by the pattern. Count the visible V shapes only. Do not count the slip knot or the active loop on the hook, and keep the chain untwisted.

Slip stitch, single crochet, and half double crochet

Complete one four-image sequence before moving to the next stitch.

Slip stitch (sl st)

Single crochet (sc)

Half double crochet (hdc)

Slip stitch step 1: Insert the hook

Slip stitch · Step 1

Insert the hook

Insert the hook into the indicated chain, stitch, or space from front to back.

Slip stitch step 2: Yarn over

Slip stitch · Step 2

Yarn over

Catch the working yarn with the hook so it wraps over the hook from back to front.

Slip stitch step 3: Begin the pull-through

Slip stitch · Step 3

Begin the pull-through

Draw the yarn back through the stitch. Keep the hook facing downward so it does not split the yarn.

Slip stitch step 4: Complete the stitch

Slip stitch · Step 4

Complete the stitch

Continue pulling through the loop already on the hook in the same movement. One loop remains. Slip stitch has almost no height and is useful for joining rounds or edging.

Single crochet step 1: Insert into the next stitch

Single crochet · Step 1

Insert into the next stitch

Insert the hook under the top two loops of the next stitch unless the pattern specifies a different loop.

Single crochet step 2: Pull up a loop

Single crochet · Step 2

Pull up a loop

Yarn over and draw the yarn through the stitch. Two loops should now be visible on the hook.

Single crochet step 3: Yarn over again

Single crochet · Step 3

Yarn over again

Catch the working yarn once more while keeping both loops open and even.

Single crochet step 4: Pull through both loops

Single crochet · Step 4

Pull through both loops

Draw the yarn through both loops together. One loop remains and the US single crochet is complete. In UK terms, this is double crochet.

Half double crochet step 1: Yarn over first

Half double crochet · Step 1

Yarn over first

Wrap the yarn over the hook before inserting it into the next stitch.

Half double crochet step 2: Insert and pull up a loop

Half double crochet · Step 2

Insert and pull up a loop

Insert under the top two loops, yarn over, and pull through the stitch. Three loops are now on the hook.

Half double crochet step 3: Yarn over again

Half double crochet · Step 3

Yarn over again

Catch the working yarn while maintaining the three loops at an even height.

Half double crochet step 4: Pull through all three loops

Half double crochet · Step 4

Pull through all three loops

Draw the yarn through all three loops at once. One loop remains. The US half double crochet, called half treble in UK terms, is complete.

Double crochet, rows, and stitches in a ring

Use each photograph independently and read the full action underneath it.

US double crochet step 1: Yarn over and insert

Double crochet · Step 1

Yarn over and insert

Yarn over once, then insert the hook under the top two loops of the next stitch.

US double crochet step 2: Pull up a loop

Double crochet · Step 2

Pull up a loop

Yarn over and draw the yarn through the stitch. Three loops should be on the hook.

US double crochet step 3: Pull through two loops

Double crochet · Step 3

Pull through two loops

Yarn over and draw through the first two loops only. Two loops remain.

US double crochet step 4: Finish the double crochet

Double crochet · Step 4

Finish the double crochet

Yarn over again and pull through the final two loops. The US double crochet is complete; the UK name is treble crochet.

Working in rows step 1: Finish the first row

Working in rows · Step 1

Finish the first row

Work across the foundation chain in the direction specified by the pattern. At the end, check the stitch count before turning.

Working in rows step 2: Turn and begin the next row

Working in rows · Step 2

Turn and begin the next row

Make the turning chain required for the stitch height, turn the fabric, and identify the first stitch. Follow the pattern rule for whether the turning chain counts as a stitch. Count each completed row to keep edges straight.

Working stitches into a ring step 1: Work into the center

Working into a ring · Step 1

Work into the center

Create a foundation ring or adjustable magic ring. Make any required starting chain, then insert the hook into the center of the ring rather than an individual chain loop.

Working stitches into a ring step 2: Complete and close the round

Working into a ring · Step 2

Complete and close the round

Work the required stitches into the ring. Pull the tail to close an adjustable center. Use a stitch marker for continuous rounds, or join with a slip stitch when the pattern calls for joined rounds.

Treble and taller crochet stitches

The four photographs below show US treble crochet. Double treble and triple treble are explained completely afterward.

US treble crochet step 1: Yarn over twice and insert

Treble crochet · Step 1

Yarn over twice and insert

Wrap the working yarn over the hook two times, then insert the hook under the top two loops of the next stitch.

US treble crochet step 2: Pull up a loop

Treble crochet · Step 2

Pull up a loop

Yarn over and draw through the stitch. Four loops should now be visible on the hook.

US treble crochet step 3: Reduce the loops in pairs

Treble crochet · Step 3

Reduce the loops in pairs

Yarn over and pull through two loops. Repeat once more, leaving two loops on the hook.

US treble crochet step 4: Complete the treble

Treble crochet · Step 4

Complete the treble

Yarn over and pull through the final two loops. The US treble crochet is finished. The equivalent UK name is double treble.

Complete technique

US double treble crochet — dtr

  1. Yarn over three times.
  2. Insert the hook into the next stitch, yarn over, and pull up a loop; five loops are on the hook.
  3. Yarn over and pull through two loops four times until one loop remains.
  4. For the next row, follow the pattern’s turning-chain instruction and work into the correct first stitch.

Complete technique

US triple treble crochet — trtr

  1. Yarn over four times.
  2. Insert the hook into the next stitch, yarn over, and pull up a loop; six loops are on the hook.
  3. Yarn over and pull through two loops five times until one loop remains.
  4. Use the turning-chain height stated in the pattern and confirm whether it counts as the first stitch.

Frequently asked questions

Skill FAQ 1

Which hook grip is best?

The pencil and knife grips are both valid. Use the one that keeps the hand and wrist relaxed.

Skill FAQ 2

Why is my chain too tight?

Relax the yarn hand, avoid tightening after every chain, or try a slightly larger hook for the foundation only.

Skill FAQ 3

Does a turning chain count as a stitch?

Sometimes. Follow the rule stated in the individual pattern.

Skill FAQ 4

Are UK and US terms interchangeable?

No. The same stitch name can describe different techniques, so confirm the terminology first.

Skill FAQ 5

When should I use a stitch marker?

Use one for the first stitch of spiral rounds, pattern repeats, shaping points, or any place that is easy to lose.
