Thank you for checking out this pattern! The Starlight Headband is a fitted headband and ear warmer that can be customised in many ways. From the colour to the size, once you have the basic stitches, you will be able to create your own unique accessory. Included in the pattern are the instructions for the following sizes: 0-3 months 3-6 months 6-12 months Toddler Child (3-10 years) Teen/small adult Large adult The great thing about this pattern is you will be able to make the headband fit perfectly as all the sizes are provided on the front page. I have used 8ply yarn for this pattern, but you can use any ply. I have used a 5ply and a 4ply in other versions of the headband. As long as you make the first round the dimensions provided, you can use any combination! I hope you enjoy this pattern!
