I love basting spray! I am a recent convert to the 505 from June Tailor and Dritz. The 505 is so much better. No smell, no fumes, no fingers sticking to everything else I touch, no gumming up the needle. The issues I had with the needle gumming up drove me nuts before. I had problems every few inches it seemed...it really slowed me down. The 505 is a little more expensive, but I use less of it, so it probably works out the same price wise. Plus now that I know I like it, I can shop for the best deal (Walmart online or Connecting Threads sale prices aren't bad). I spray in a grid pattern, every 6-8" or so. I spray inward from the edges, so no overspray to the surrounding area. Best of all...no wrinkles in my quilt! I love it!
