When I asked my 4-year old DS what he wanted for Christmas, along with the usual list of toys, he asked for a rainbow hat.
I had a couple yarns in my stash that fit the rainbow requirement, and he chose the yarns that I spun from the fiber that we had dyed together.
The yarns were all ombres, going from neon to pastel. I just used the neon section of each yarn (with the exception of the last one), resulting in a nice variation in the width of each color. DS chose the order of the colors and wanted a white poof ball. He thinks wool is itchy (even Merino), so I lined it with a bit of fleece leftover from making Hobbes. I’ve never lined a hat before and I’m sure it’s far from perfect. But, my boy likes his hat and that’s good enough for me.
