I had the same problem, what I did was go to the hardware store and bought a large sheet of plexiglass and dry erase markers..
I then lay it over my quilt and play with designs! I have a piece of paper and pencil
To draft what I decide!
I also have traced designs onto tracing paper
And pinned them to my quilt. I have quilted onto the paper but I don’t recommend that..
Picking the little bits of aper out from your stitching isn’t fun!
