I've only used the basting spray once and hated it. I just pin baste. It takes a while but I've never been unhappy with the results on my quilting using pins.

I used spray baste for the first time yesterday, and I have June Tailor. It was a bit wrinkled so I had to peel it apart and re-smooth out several sections. But I thought it was just my inexperience that caused it. Or maybe that spray basting works better on smaller quilts (this one is lap sized). I'm tying this quilt, so I guess I won't know what it does to my machine. One thing I did notice is that it's not keeping the edges together. I think I'm going to pin along the border before I start tying.

But now I'm nervous using the spray basting spray on my next quilt!

I use spring clamps with my cutting table and large safety pins for basting....works like a charm.

I'm fairly new to quilting and love to spray baste! I tried the other brands mentioned here, but 505 is the best, IMHO. When I complained to the shop owner where I bought my machine about the "gunked up" needle, she said I was using too much spray. I used less the next time and problem solved! In a quilt class I was taking, the instructor taught us to spray baste. It is much easier if 2 people do it, so I put my quilt on tables covered with an old tablecloth, DH and I work together to work from the center and move out. The 505 is very forgiving and it's easy to move if you have a bump or wrinkle. The instructor told us to use our largest ruler's edge for smoothing, but I like my hands. One big item- NEVER spray the fabric! Always spray the batting- don't know exactly way but it does work better!

I use the 505 all the time. This is for small items only. I have a frame to quilt all lap and bigger quilts. What I do is - lay the backing down and iron it - starch it flat - spray - not too much -lay the batting down and smooth with your hands many times until there is no more give to it - lay the top on the batting. The top has been starched so it lays smooth and flat. Smooth with your hands again so there is no wrinkles or give. Pull half of the top back and spray that area. Now, pull that back onto the batting and smooth that in place. Next - pull the other half back and do the same thing you did with the other half. Sometimes it takes more than just halves.
When I get done spraying and smoothing, then I iron both sides to get the whole thing flat. I iron it from both sides. Just remember not to use too much spray.

I use June Taylor all the time, so far for 120+ quilts and have never had the problems you explained. My first thought when reading your post was that you sprayed too heavily. Also, when layering, I use a different technique. I cover my bed with a large flannel sheet, smooth the back down, arrange the batting on top then fold back half of it and spray it sparingly, then carefully smooth it back down and repeat the process for the other half. Then arrange the quilt top on the batting and repeat the fold back, spray, and smooth down process. The trick is to spray sparingly and give it a few minutes to set up. Some fabrics take to the spray better than others and you can always lift the layers and squirt a bit more if needed. Give it another try on a small project. It is such a back/knee/time saver and so worth the effort.

If you have the room get yourself 4 boards and clamps and thumb tack your pieces to these boards and there is no need to baste.

I use spray all the time, with good results. I like Sullivan's the best. (pink can) You can get it at Hancock Fabrics. I have tried Dritz, and threw the can away- did not like it at all. I'm also not crazy about June Taylor.

Yeah, the 505 is wonderful. I get mine from Connecting Threads.
