I spray baste and then safety pins just to make sure the spay worked...check & double check I guess. I am still in the learning process so it's SID for me

I have used pins and spray basting. I like spray basting better. Just DON'T use a lot. Just a light spray will do.

if your spray basting is loosening, just run a warm iron over it unless you have markings on the quilt. You don't want to set those into the fabric. Have fun, practice on a sample block and enjoy the heck out of it

Thank you all for sharing your time and expertise. I will be utilizing quite a few of these suggestions from now on.
