I've used spray basting a couple of times (pink and white can). I really like the shortcut and not having to thread baste. I've broken too many needles with pin basting, ya, stupid huh! I have an acrylic sewing table and the sticky over spray really adhered to the surface and made it tacky. Should have washed off with soap and water being water soluable, but hasn't. The other issue I've experienced is while smoothing the quilt top, the bat material seems to stretch and causes the back to ripple. I'm sure it's my technique; any solutions anyone?
