That's a cute and different one!!
Great work!
Leather buttons, huh???...sound like good noses for some little stuffed animals!!?? :) You could even use the sleeves for the animals.
Maybe even sorta follow the directions for a sock monkey with the sleeves, as it takes two socks for one. Start by sewing one end shut on both sleeves to make the "sock". ???
or there is the elephant....
