The Gaia dress is a made to measure and size inclusive design, this means that you take your own measurements first as indicated in the pattern and then follow the instructions. This means it can be made for any size and age.
The pattern is a advanced beginner level that uses US terminology.
The pattern contains written instructions, stitch graphs and photos throughout making it easy to follow.
You will need any type of 4ply (fingering weight) cotton yarn and a 3mm crochet hook. You can use other types of fibers but please note the gauge may differ.
For the sample size (UK 6), I used roughly 1400m of yarn.
