When I saw this fabric all I could think of was a special 18 month old little boy very dear to me. One of the patterns I purchased was a pattern of several toddler hats. I changed it a little bit because I wanted to make it adjustable. I cut out the hole in the back and added an adjustable velcro strip to the back. If I had it to do again, I would make the bill stiffer. Live & learn. I hope it fits him! Even if it doesn't, it was a lot of fun to make!
