My three must have adhesives for when I am paper scrapping are:
Thermo Web Memory Tape Runner XL
Pop Dots and Mini Pop Dots for dimension
and my Sakura Quickie Glue Pen for those very thin pieces of cardstock or pp, for glueing down small punch outs like ferns, leaves, flower petals, etc., for glueing down border strips like Doodlebug Paper Frills, and for glueing down anything that is too narrow to glue down easily. It is so fabulous because you just write with it like a pen and it puts glue down just like a pen puts down ink. I LOVE it! (No pic because ACOT doesn't carry it.)
