Jenwa at Ramblings of a Crazy Woman and Filth Wizardry featured homemade flip flops. We couldn't resist trying this one at home.
Foam Craft Sheets or Cardboard
Chenille Stems (Pipe Cleaners)
After attaching the pipe cleaners - I glued a second foot shape on to hide the pipe cleaners. This also made the sole a bit more cooshie. Visit Ramblings of a Crazy Woman for full instructions. I like how she used card board and had her kids decorate their own (great for older kids.) The foam sheets made this a fun and easy craft for toddlers. Adult assistance is a must for small children. Done on a smaller scale this would be cute as a gift tag. Have fun crafting with your kids.
Edit: I forgot to mention we made the flip flops on 2 different days (actually over a week apart.) I try not to push my kiddos to finish a project. I just put it aside until they are ready to try it again. Usually I will let some time pass and take it out the next craft (Emme's nap) time and see if Lu is interested in working on it again.
