I add a small amount of hot water to the glue, and it streams out with no effort at all. I hold the bottle up high and let it stream out on the batting in a thin line. Like fmqing with glue. LOL. I smooth the backing on, let dry and turn over and do the same with the top. I press it if I want instant dry.
I got the idea of diluting a lot to make stiff starch. The diluted glue burned fast with a hot iron though.
