I've never even heard of that Celeste - but I'll definitely check it out!! Cordless sounds awesome!
I use my hot glue gun ALL the time! I get those little stringy glue threads too Andrea, but they don't bother me too much - I just give them a little yank and they come right off. I usually only get one thread for each thing I glue and don't have trouble pulling them off. Hot Glue is my preferred adhesive for bulky or heavier embellishments - buttons, paper flowers, felt, etc. And if I'm working, my glue gun is pretty much plugged in and ready to go. But I'm totally paranoid about forgetting to unplug it and burning my house down or something! (I'm sure this would never happen, but it's one of those recurring little things - like every time I leave the house I have that nagging feeling of "did I unplug that glue gun?").
Aren't we funny how we each have our own individual preferences? I seem to be one of the few who likes to use Mod Podge too.
