While I was typing, you posted the pic ... I guess for me, I would want more orderly, as in every block the same size. That would work well with your FQs, using 1/4 of each for a block. You can do the math as to what would work for the size of your quilt. What about using Christmas colours for the background and the shadow?
Another one ...

Similar effect ... but because of the size of your balls you would need to do it with larger pieces to show off the balls. Again, do the math as to whether you could make anything of enough size. I'm not sure you could. BTW I saw this one done at one of the Fairs in all florals .... the mortar between was in a cream. So pretty! (and yet so scrappy!)
Or .... how about a runner? or topper?
then you could keep your fabrics in large chunks.
Googled to look for a pattern ... not this one, but I think it could show off your fabric nicely,
Anael!

Funny how when we google, we land right back here on the QB!
