I have never used glue, but in thinking have decided that it would be a big help in certain situations. My question pertains to using the iron on the spots with glue. I use the iron alot while piecing the tops and am wondering if the glue will still wash out ok after having been ironed? I can't wash out the glue until the quilt is done, can I? And obviously can't wash every time I use a bit of glue. I just don't want a hard nasty spot that won't wash out.
