Hmmm, only one top came to mind immediately, then I remembered the one hanging on the wall in front of the closet door in my sewing room, then I remembered the wall hanging waiting to be sandwiched and quilted, and then of course there's the little wall hanging I'm making for fall... so I guess that makes 3 or 4.
I usually either send a top to a longarm quilter or tie it. I am currently finishing up my first attempt at machine quilting one myself. It's far from perfect. Gotta start somewhere I guess.
