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."
