What do you do? I usually pin my quilts. I have friends that use spray adhesive and ones that pin. And I have friends that work small art quilts, so they don't have to do either. I've tried spray basting before, but the quilt still shifted and I didn't like the layer of adhesive going through my machine and gooping up my needle. I just grab my bowl of quilting pins and Kwip Klip and pin.
Oh, like my little bowl? It is very special to me. My step-son made one year in elementary school and gave it to me for Mother's Day. Sweet memories every time I see it and use it. I've been using it for over 20 years now!
My worktable was designed so the height is easy for me to pin on, really saves my back. I use binder clips on the edges to hold the layers in place and depending on the size, I may use blue painters tape too.
So, my quilting friends, what do you do? Let me hear from you!
