Recycled sweater super hero fingerless mitts

I have a custom order for kids armwarmers, so as usual I've made the
prototype for my son
When I asked if he wanted me to appliqué something on them (I put a
lot of stars on things), he said yes but he wanted to make the
patterns for me
So he drew & cut out a triangle & a "circle w/ a flat side"
We decided they looked like superhero gauntlets.
