I learned to spray baste-no pins!
 

I have found that these tips work for me when I use a six foot folding table to layer my quilts for quilting.
Iron the batting and spread on table.
Arrange top of Quilt over batting.
Work with half at a time to spray baste.
Repeat with backside.
Anyone's advice/tips appreciated.

This is my method as well. The only I add is after the top is spray basted to the batting, I press it again and then add the backing and repeat with ironing from the backside. The advantage is you can use less spray baste and it holds just as well.

May I ask which spray you use?

I also put a safety pin on the center side of each layer. That way I know I am getting the layers put together and lined up good.

I use the ironing board spray basting technique. It works very well.

I loved spray basting until I discovered basting with Elmer's Washable School Glue. Now I am addicted to Elmer's it is so much more secure than spay basting. I spray baste the same way you do. The process is pretty much the same way with Elmer's. There are a number of good YouTube videos to teach you the technique if you are interested.
Spray basting is perfect for larger or smaller quilts and perfect for baby quilts as long as the quilt is washed before given as a gift. Looks like you have a handle on the spray basting.

followed this link today. will be ordering clips for next quilt. thanks to whoever posted it.

I like 505. I use a few safety pins here and there for large quilts. I use pretty much the same process as the OP, but start with the batting and backing first, then flip and put top on. Once top is on I let sit for at least 24 hours. I've found that it is quick and easy, but it is also easy to get overly enthusiastic with the amount of spray which then can gum up your needle and cause thread breakage. This can be remedied by using anti-glue needles if you're quilting on a domestic, but so far I haven't seen any anti-glue needles for mid arm or longer machines.

No tips as I don't spray baste often, but curious what batting you use, that you actually iron it?

I just use regular cotton warm and natural batting. It was at the end of a roll and had lots of wrinkles.
