I had a hard time figuring out how to get his hair to look right, I'm not 100% happy with it, especially the back but it's not awful. It was a lot of work though. I'm really happy with the Superman logo, it's not perfect but I like it! I gave him a bit of a crooked smile, I think it's cute.
For the cape, I used a new to me stitch called the waistcoat stitch. It looks like knitting, I love it!
The birthday boy loved his Superman! Eventually, I'll be making a Spiderman and a Batman too.
