OK, I've crawled out of my cave again and I am intrigued.....what is an Accuquilt and what does it do? I am saving my pennies (lots and lots of them) for an embroidery machine, but I have been hearing a lot about Accuquilt. Is it expensive? (silly question, huh? almost everything related to quilting is expensive. haha) Thanks for any explanation you can give.....Merry Christmas!
