I love spray basting. My first two quilts I used way to much and had over spray. After watching Jenny and her daughter I realized I used to much spray. The next quilt worked a lot better. I put my backing on my design wall and spray it then add my batting, spray and then add the top. I love using my design wall to spray bast. I do pin newspaper around the edge of the backing. I couldn't find 505 in the stores and so I used a can from Walmart and it held just fine and no gummy needle.
