LadyRags,
I do my own quilting for most of my quilts which are about what I think you are thinking of as "lap quilt" size. If they get much bigger than 50 or 60 inches square, though, I find them a little hard to manage on my domestic machine. Medium-sized Wall quilts, table runners, smaller lap quilts, baby quilts, quilted vests and jackets, all work very nicely on a domestic machine, I think. Then there's the intriguing "miniature" quilts I've been experimenting a little with. (The American Quilting Society categorizes those as smaller than 25 x 25 inches--they don't have to be square of course, but can't be wider or longer than that).
I really think these are loads of fun to make.
