See, here is her sketch of what she wanted me to make.
....And here is what I made! Pretty close! I think it was drawn as a bat ninja, hence the sash tie on the right and the crosswise thing (a bow case strap?). I was going to add the cross strip in felt, but it interfered with the bat signal detail at the waist.
He's coming to get ya! The only thing I would improve is the stumpy wings. She had them drawn stumpy and I am running out of felt, so I only could make stumpy, but I feel like the body needs bigger wings to balance it out. Next time.
The end.
Enjoy! Wendy
