I hope I'm not being a pain and flogging the dead horse by asking all these questions, but what is obvious to those who are experienced is not so obvious to me.
Lois, the Elmer's School Glue is another option I like and am definitely looking into. I don't mind hand stitching (I say that now, but...) so the water-soluble thread option is appealing. Pulling out the stitching as you go is counter-intuitive to me (when you're in the fluid mode of drawing with stitches to repeatedly stop) but as yet I don't have enough experience to reject that option either. Only experience can determine our individual preferences and techniques.
