Check out the “Let it Snow” Xmas 2020 Group youtube project!”
cid - I was looking thru some older threads & I love your posts! I appreciate the information.
BTW, I saw a cellist that had a narrow, deep cloth (or leather) pocket in front of the tail piece! It was "cone" shaped so he could quickly place his bow into it.
I don't know if it was custom or commercially available, but I could see you Quilting one!
cid - I'm so sorry, it was a "Bass Bow Quiver". I actually saw it on a Double Bass.
Fiddlershop has one, but I saw many different ones when I googled images!
You may want to modify the shape and placement a little for your Cello.
Here's basic instructions for sewing one - I still think it would be a cool quilting project!
