Every top I make, i quilt. I never have tops sitting around BECAUSE my grandmother has bags full of tops that she never got the time/money to quilt or have quilted, and I don't want all my work to just sit there, not being enjoyed. That's also why I've learned to quilt on my regular sewing machine.
I don't worry about storing my quilts, because I give 90% of what I make away, as gifts or to charity. And I have plenty of storebought blankets that can become "camping blankets" and be stored out in the shed when I need the room in the closet to store my finished quilts. As of yet, though, I don't have any bed-size finished quilts to store. Soon, though.
