Thank you all for your suggestions! I'm going to try the 505 and I saw one post here with Sulliivan. My next question: when fmq'n does the needle gets gummed up from the adhesive? I know I should be looking this up on youtube and such but I prefer to ask those who have done it! Thanks again all for the ideas.

Thank you for all of this information. Allergies have driven me away from even trying spray adhesive. So far, strong hair spray (DD calls it "hair cement") works for small projects! It really does!

One of the reasons I prefer 505 over Sullivan's is the odor; 505 is much less smelly. However, you still want to have good ventilation when using it. Another good choice is Therm-o-Web, probably even better than 505. It comes out as a web so there is less overspray and I assume less volatile particles in the air.

I do not know of anyone who has gotten a gummed up machine needle from 505 or Therm-o-Web. I have read rare posts about gumming and/or discoloration caused by basting spray, but they were always off-brands and also often very old cans.

I starting spray basting my FMQs after watching a class on Craftsy and part of the process is to press after spraying and layering. It works for me.

I use whichever I find at JAF. Since no one taught me how, I do it the same way I used to do pin basting. Tape backing to floor and spray the batting to it. Then I spray the quilt top to the backing. I understand this may be the wrong way...but it works for me. No wrinkles. I do let it dry for a day before quilting it.

I like 505 the best. It doesn't 'gum' up your needle.

Elmer's Washable School Glue is my stand-by, even for hand quilting, never a shift or wrinkle. No smell, no over-spray, iron as you go to dry glue, does not gum up needles (machine or hand).

I have used only 505,but I am learning to use glue-basting.

Elmer's School Glue is my go-to basting product. No odor, no over-spray, washes out completely, doesn't gum my needle, no wrinkles, nothing ever shifts, even Minky. I wouldn't use anything else.

Again thank you all! I went to Joanns today and bought the last 505 can of basting spray and thank you for confirming that the needle won't gum up.
