I just read Just Jan's post. I also use spray baste for my quilts. I sprayed one a few nights ago and ironed it to dry it a little as I wanted to start quilting right away. I put it under my brand new epic and proceeded to break thread continously. After I cleaned everything and changed needles many times, I quit. The next day ( quilt was dry, duh) I had NO trouble. I found that freshly sprayed does Not work for me!! I am jealous that Jan is able to go right to the task with no waiting. I am still practicing with the school glue. If you buy the spray on sale, use a mask and go easy on the amount, it is just so much simpler!
