Yikes. I was in a class and the lady next to me used the purple color. Even though it says 'dries clear' when she put the iron on it - instant stain. I love using the sticks, but only the white.

Beautiful quilting--can't wait until you can show us the front.

I use glue basting and it is one of those “figure out how it works for you” things. For me, I bought a gallon of Elmer’s school glue, and pour it into a picnic type squeeze bottle (like you put ketchup in) and holding it about 10”-12” above my surface, squeeze as evenly as I can, make swirls around and over each other aiming for about four inches between the lines of glue. I do half the quilt at a time, and DH helps me roll the top layer back over the glue. Smooth, and allow to dry or you can speed it up using an iron with a Teflon press cloth to catch any glue that seeps through, or use a blow dryer on high, held four inches above the fabric. Works for me.

I use the purple Elmers glue sticks when I am piecing instead of pins. Too many years of garment sewing to be able to go no pins cold turkey. Lol! Thanks for the info about the stains- I hadn't noticed any yet because I am using colored fabris *so far*. Glad I saw it before I started on the white sashing!
I have my washable Elmer's all diluted and ready to go, I'm just too chicken to try it so far. All us glue chickens should make a wall hanging or something and try it. It'll be like a 12 step meeting. "Hi, I'm Patti, and I'm afraid to glue baste."

My first glue baste was a 12” x 18” wall hanging, using light and medium fabrics, no stains after washing Worked great, but I watched a lot of videos first.

You should make a test, could show some yellow on back if tension is off.
