Free Rainbow Brite Crochet Wig Pattern

Create a bright Rainbow Brite-inspired yarn wig that’s perfect for costumes, Halloween, dress-up, or a colorful handmade outfit. The yellow wig, long side ponytail, playful bangs, blue ribbons, and red star create the fun character look while keeping everything soft and comfortable to wear.

Quick answer

This beginner Rainbow Brite crochet wig is made with worsted weight (#4) yarn and includes six sizes from 0–3 months through adult. The yellow beanie is worked from the top down in joined rounds with an I-9 (5.5 mm) crochet hook, then yarn strands are added for the ponytail and bangs. A red crochet star and two blue ribbons are made separately with an H-8 (5 mm) hook and attached to the ponytail.

Gauge

15 stitches and 10 rounds = 4 inches (10 cm)

My guide to crochet gauge explains how to measure your stitches and adjust your hook size.

Crochet abbreviations

dc = double crochet
sc = single crochet
ch/chs = chain/chains
st/sts = stitch/stitches

Pattern notes

The chain at the beginning of each round does not count as your first stitch.
Join each round with a slip stitch to the first stitch made in that round.
Repeat instructions between the asterisks (*) for the rest of the round.
The beanie is worked in joined rounds from the top down.
The pattern is written in US crochet terms.

Magic circle alternative

If you’re not comfortable using a magic circle, you can use this alternative method for Round 1 of the beanie.

Tie two more pieces of yarn around the ponytail further down and secure it to the side of the hat.

Bangs instructions

Cut short strands of yellow yarn. Tie the strands around the stitches on the last few rounds along the front half of the hat. Add enough strands to create the fullness you want, then trim the bangs to the desired length.
