Duck Tape Wallets

There's no real duct tape gallery, so textiles is as close as it gets. I made these today on my, what, fifth? day of summer vacation. I hope to sell them. I calculated costs and each wallet only cost about $0.67 in duct tape, but each one takes me about an hour to make. (Hopefully with practice I will shave that time down.) I was thinking $5 but my mom said anything up to $10.

What do you all think is a good price for these?

Sorry about the shine. It's kind of hard to see the ducky feet. =/ (Hehe, get it? DUCK tape? Oh, whatever.) The colors here are a bit off, too. The pink bow tie is more like florescent Barbie pink than what is shown here.

Please give me your design suggestions and comments and let me know if you want one! I can also do names and such thanks to my handy-dandy exactoknife set.
