I remembered, from the dim and distant past some Papermania Signature, paisley patterned, vinyl stickers I’ve had for years and wondered if they would work on the hearts, and after a long winded search through several boxes of bits found that they did! Result!
After arranging and sticking the stickers on the heart and trimming away any excess from around the edges I then remembered a packet of flat backed, pearl patterned strips that Dianne in Florida sent me from Michaels and wondered if they would work too ……. and again, I think they did!
