Thanks Pam, I think a heat gun would blow the tls around and spread it more, but I think you are on the right track. There's an article in the new (Nov/Dec) Bead & Button by Carly Siebel www.geocities.com/lubellebeads
for another type of faux lampwork with raised designs in TLS. She not only applies the tls to the bead while it is hot, but she also does a little and then pops the bead in the oven for a few minutes and then does some more. I am going to have to try some of her tricks. Right now I just work very very fast.
