I have used Elmer's School Glue or Roxanne's Basting glue since I started quilting and couldn't get my seams to match. :D Sometimes I glued a tiny teeny point of fabric to get my point back that I cut off in the seam. :wink:
I bought the glue tips Sharon uses the first time I saw her use them. They are heavy weight and the tips are long giving a even very fine line of glue. I didn't know the mech. pencil trick. That's nifty. Did you know, Elmer's School glue is a very heavy starch not a glue.
