On the laminating subject . . . I'm using the clear packaging tape that I use when I box up my bears for shipping. It's just the right weight/thickness (so that my hang tags will still bend in the middle), I already have it on hand, and it's really inexpensive.
Yes,the clear stuff.Can be called mac-tac.You just have to be very careful when sticking to front and back because it grabs and hold the paper.I have ruined one certificate by being in too much of a hurry.It works out to be cheaper than laminating.
At least we are honest Clare,lets just think of our wrinkles as "wisdom spots" you know like "beauty marks",soon everyone will want some
