I was at walmart today, and saw that mine just got in these new high temp ( I use high temp ones because I am slow, so it gives me more time to get things in place before it dries) glue gun that has a narrow tip so that you can get into the small spaces with it. It was under $5 (can't remember now exactly how much it was) and it was a mini one. I can't wait to use it. I don't have any projects right now as I am waiting for my inspections to come back. (sent in my evil horse for yet another inspection) I think this gun will make a big difference for me as I have a tendency to be a bit messy with the glue gun in the small spaces. I might actually be able to get a small thin bead with this one. Maybe tomorrow I will try it on some scrap fabric just to see how it goes. I'll let you all know.
Inel-I'm sorry those circles are giving you such a hassle. Guess every project has it's tough spots.

Hang in there, maybe it's something that will get easier the more you do. Hopefully!
