My entry for August's VSNB challenge; had to use cardboard, so there they are on the soles!
I just stamped the Tropical Blossoms on off-white cardstock (made lots so I could go back and make more). Then I used this flip flop template, shared by Jusgottastamp. I drew the soles slightly larger than the template.
I punched 3 holes then added the ribbon. I used a brad to keep the top ribbon in place and to make it look authentic. :cool: The ends of the ribbon are just taped down. I used my favourite double-sided, strong, sticky tape to adhere the top & soles together.
