I'm between tops on the frame so I put some scraps from a large backing and scrap batting on to practice. It is fun to do but it takes more control than what it looks like when watching someone who knows what they're doing it.
I think that I need to map out what I'm going to do, even if it's just some quick lines and general guides of where to go.
Someday I'll get up the nerve to do it on an actual quilt! :P
