Thanks for your suggestions, ladies! I've always used either the glue gun or fabri-tac, but they're either too bumpy or the glue shows through. (I'm such a perfectionist here!) Astrid suggested that I use the ATG without the holder, so I think I'll try that.
I would like to know what you use to glue ribbon onto paper/cardstock/chipboard.
I've heard that Scotch ATG is awesome, but I'm a lefty and the ATG is built for righties.
