Here is one of the towels, with the accompanying card. The card base is kraft cardstock, with some Hero Arts cupcake images, and a sentiment by Studio G. Some rhinestone bling finishes it off.

And here is another version. Normally I embroider on plain microfiber towels, but Kohls usually has such cute towels for Halloween, Valentine's Day and Easter, that I purchase the towels from there, and add some embroidery.
Have a Happy Valentine's Day, everyone!
