I love glue basting. I just washed a quilt I finished today that I had glue basted. I found that the glue comes out best for me when I use warm water. I usually wash in cold water. I also used a water soluble marking pen to do the quilting for the first time and that worked wonderfully as well. I did wet down the quilt with a spray bottle to get those marks out as it said not to use detergent to get it out and I wanted to used detergent to get the glue out.
