I use the pattern for the flip-flop card and cut it out on chipboard; then cut out another on cardstock. Line up the dots for the "thong" and I used ribbon and brads for the thong; I have also just cut out the thong from CS and embellished it with punched flowers. I got the magnetic tape at A.C. Moore and you simply cut off about 1/2" and stick it to the back of the flip flop near the top and then another 1/2" piece near the heel.
Here are some of mine:
