This is an easy and colourful pattern that little rainbows of all ages will love. Four sizes are given - baby, toddler, child, and teen/adult - with guidance on further adjustments for smaller or larger heads.The skills required are beginner level - you will need to be able to cast on, knit in the round, purl, and to knit two stitches together.This pattern will take you through the colours of the traditional rainbow in the conventional order (red, orange, yellow, green, blue, indigo and violet) with all the colour changes clearly indicated and the decreases mapped out so you don't need to worry about the arithmetic and can just get on with enjoying the knitting!
