Colourful crochet projects by MrsCrochetWorld

Basic stitches

The essentials

Chain (ch)
The foundation of almost every project — a row of interlocking loops.
Slip stitch (sl st)
A flat, short stitch used to join rounds or move across without adding height.
Single crochet (sc)
The workhorse stitch; tight and sturdy — the heart of amigurumi.
Half double crochet (hdc)
A touch taller than sc, soft and quick — lovely for hats and scarves.

Taller & textured

Double crochet (dc)
Tall with beautiful drape — perfect for blankets and garments.
Treble crochet (tr)
Even taller; creates an airy, open fabric.
Bobble / Popcorn
Clusters that pop off the fabric for texture and 3D detail.
Shell stitch
Several stitches worked into one point, fanning out like a shell.

Common abbreviations

Stitches & actions

inc / dec
Increase / decrease — add or remove a stitch to shape your work.
st(s)
Stitch(es).
rep
Repeat.
yo
Yarn over — wrap the yarn around the hook.
sk
Skip.

Placement & counts

FLO / BLO
Front / back loop only — work into just one loop for ridges or seams.
MR / magic ring
An adjustable starting loop for working in the round (key for amigurumi).
rnd / row
Round (worked in a circle) / row (worked back and forth).
( ) x6
Repeat the sequence in brackets six times.
💡 Tip: US and UK crochet terms differ! A US single crochet (sc) is a UK double crochet (dc). All MrsCrochetWorld patterns state which terms they use.

Yarn & hooks

Yarn “weight” means thickness, not how much it weighs. It runs from 0 (lace) to 7 (jumbo) — the thicker the yarn, the bigger the hook and the faster your project grows. For a full chart, see our Yarn & Hook Size Guide.

Yarn terms

Worsted (CYC 4)
The most popular all-rounder — great for toys, bags and blankets.
DK (CYC 3)
Slightly finer; lovely for amigurumi and garments.
Gauge / tension
How many stitches fit in a measured square — controls finished size.

Hook basics

Hook size (mm)
The metric diameter — e.g. 4.0 mm. Smaller hook = tighter fabric.
US hook letters
e.g. G-6 = 4.0 mm, H-8 = 5.0 mm.
Tighter for toys
For amigurumi, go a size smaller so stuffing doesn't show.
Crochet amigurumi and accessories

Techniques

Shaping & assembly

Working in the round
Crocheting in a continuous spiral — the basis of amigurumi.
Invisible decrease
A neat decrease that hides the join — perfect for toys.
No-sew / low-sew
Patterns designed so parts are crocheted on, minimising sewing.

Finishing

Weave in ends
Thread loose tails back through stitches so they disappear.
Blocking
Gently shaping & setting finished pieces with moisture.
Stuffing
Polyester fibrefill, added firmly & evenly for a smooth shape.

How to read a pattern

A line like “Rnd 2: (sc, inc) x6 (18)” means: in round 2, repeat “one single crochet, then one increase” six times — and you should finish with 18 stitches (the number in brackets is your stitch count). Always check your stitch count at the end of each round. New to this? Start with an easy beginner pattern or grab a free pattern to practise.

Glossary FAQ

What does “MR” mean in a crochet pattern?

MR = magic ring, an adjustable loop you start amigurumi with so there's no hole in the centre.

What's the difference between US and UK terms?

The same stitch names refer to different stitches. A US single crochet = UK double crochet. Our patterns always specify the term set.

What yarn weight should a beginner use?

Worsted (CYC 4) with a 4–5 mm hook is the most forgiving combination to learn with.
