I finally found shoes, just plain dyeable flats from Payless, but I defintely need to put shoe slips on them cause they are BORRRRRING.

I keep searching the web, but they are sort of pricey. I am thinking I can make them for under $8. I have all the supplies I need except for clips. Do they sell clips for shoes? I have heard of using clip-on earrings too!

Any suggestions?

I have seen plain shoe clips on ebay before, but I think that clip ons would work too and they have those at Walmart in the jewelry-making craft section.
