I've always hot glued my ribbon to the clips.
Then suddenly it wasn't holding very well.
I switched the gun to a new one. Nope. Tried a new kind of gun w/different heat.. like went from a regular cheapo to a hot melt. Not working.
Then I switched glues.
Even contacted the manufacturers because it was making me crazy.
They didn't know.
Am I missing something here? Do you have a preference in glue gun or adhesive brand/type?
Seems silly .. but again...>
