Things don't always do what they're supposed to. I got this fancy vellum tape so that the adhesive wouldn't show through the sheer vellum. BUT, not only did I have a 'bad scrap day', the lettering was all out of line, but the vellum tape shows through. (See the pic)
And , I did follow the instructions. Now I've got these new vellum dots and I can't wait to get back to the drawing board and see if they do what they promise.
