I like Wonder Tape. I use it to set zippers and trims really straight. It is a strip of a two-sided adhesive that dissolves away in the wash. It's kind of pricey. About $5 for this little roll. What I don't like is Wonder Tape that doesn't work its wonders. Wonder Tape definitely has a best before date.
In the photos above, the old Wonder Tape is on the bottom. The newer Wonder Tape is above.
See? Old doesn't stick to the material. What old Wonder Tape does stick to is the cardboard backing of the blister package. That's how I know if the Wonder Tape is fresh or not.
So this is what I do: I pay for my Wonder Tape and then open the package right then and there at the cashier. If it is sticking to the back of the cardboard, I'm asking for my money back.
And this is the blog post to prove my point about Wonder Tape not working if it's too old. I just pull out my iPhone and while at customer service, I show them. Because otherwise, they just won't believe me. I must have a really devious look to me, like I run a huge Wonder Tape racket to defraud JoAnn's. And I won't get a refund. (The local JoAnn's Fabrics and I, that's entirely a marriage of convenience--not a lot of love there).
