Tropit, how did you apply the glue? The first time (and last)
I applied it with a brush it was like a large piece of plywood and
definitely not fun to quilt.
Never had a problem watering the glue down. Of course you don't
want it like lemonade. It has to be fairly liquid but not too much.
I like it the consistency of heavy cream. I use a small glue bottle
with the nozzle and just apply it like drawing waves on the
batting. Then I just smooth the excess with my finger. Try it on
scraps until you find what works for you.
