The only thing I did differently was that I added a layer of insulbrite between the 2 top mitt layers of fabric.
As usual (this is becoming a trend), it took a few hours longer than originally anticipated to make. BUT it was also the first time I used bias tape properly (when I made this project I had no idea what I was doing and just kind of folded it over the edge and tried to hold it all together and sew it down all at once.
I'm happy with it. I think it turned out super cute. I ended up giving it away as a birthday present but I think I need to make another one for me.
