I clicked on the "Find tape" link and it came up. Thanks for the link Kim!

I would check Amazon. I bought a big roll there.
I haven't used it yet, so can't add too much info, but I recently got from Rob's crew at Lee Valley . . . . . I don't remember the price, but it really doesn't matter because a lot of it (money) goes there anyway .. . . . .
You can also put masking tape on both pieces and then run a bead of CA glue on the tape and stick the pieces together. The glue won't let go but the tape will and with less of a fight than PSA tape.
