I use Sharon Schamber's basting method. It's easy to do and makes a very smooth and stable quilt sandwich. She has videos on youtube.

I've only done the one quilt so far, but I spray basted it and it worked great! Came out flat as a board, and stayed that way!

I did this for the first time yesterday only I used pins instead of a needle and thread. It is as smooth as can be. It was an experience as her video shows a small sample and I had a 81" quilt and a queen size batt. The next one will go much faster, I'm sure, but it was a pleasure to be able to sandwich a quilt at home without using the floor.

I tried spray basting a queen size on the wall and was not happy with it. I had problems with the batting stretching and misshaping. When I took it down from the wall there were wrinkles all on the backing. So I took it apart and laid it on my tables (with the help of my son) and spray basted that way. Had to shift it around to get it all on the table top but i like the results better when i finished. I have used the hobss fusible and really like it also. I was looking for something that was quicker than pin basting since I have a tendency to make large quilts. However, it looks like more pin basting will be in my future - in addition to spray basting on the table.

I use her method, but usually with 505 spray instead of basting with thread these days.

Before I got my quilting frame, I would tape the backing to the floor, lay the batting out, smooth it down, tape it to the backing, lay the top down, smooth it out, tape it to the backing and then put enough safety pins in it to where I knew nothing was going to shift. It allso probably added a extra pound or two to the weight of everthing:D

i baste with a needle & thread- in a cross hatch type pattern- lines about 3-4" apart in both directions. i personally hate having to remove all the pins - pulling threads is so much easier-and for me faster- and i've not had much luck with the sprays except on small projects-always wind up thread basting anyway- so see no reason to bother (waste my money) on the sprays

I only hand quilt so don't know if this would work for machine quilting, but I baste quilt using pearl cotton and a long needle. I find it much quicker than pins. I also starch backing. Haven't tried the spray, but after reading the comments I think I'll try it.

I have always pinned mine and I have no problem with it. I am going to try something different for my knees I am \
I am using are a little too big for my skinny legs and I have a had time keeping them on. I do have a new idea and
when I get this quilt finished I am on I am going to try my new idea for the next one. (good Luck)

I absolutely never use anything but the basting spray. It works on every type of quilt I've tried it on. I do a lot of quilting on my sewing machine, not any long-arm.
