I finally found a simple mitten pattern that I liked the shape of!
Unfortunately it was for worsted and I kinda sorta ended up making up my pattern as I went. I'll find the links for the original & where I found it by the time I finish the second mitten.
Luckily I wrote down what I was doing and they actually fit.
I'm working on the second mitten now.
The yarn is Knitpicks Stroll? yarn of a discontinued color Lilypad?
Very quick and fun.
