These hats are all made from leftover yarn from previous projects. Most likely they will be given that our local children's hospital;s Knitting for Noggins program. The gray one on the top to the left was knitted using the pattern Regular Guy Beanie by Chuck Wright. The yarn worsted Red Heart I think. The top right one was knit using the Lorna's Laces Shepherd Worsted Multi yarn and pattern Palindrome Hat by Kristin Bellehumeur. The two bottom hats were knit using multiple different yarns and the pattern Scrap-happy Celebration Hat by Cosette Cornelius-Bates.
