Here is a video we found from CURLYHEADEDRED on youtube that details how to decorate footwear with seashells. We espcially like this video because it's not "staged" where someone just shows you materials, then says "do this" then they show you a perfect example of what they made. She shows a lot of the process, things that can go wrong etc. Also we see that apparently dogs like to eat shells mixed with hot glue... so be warned and maybe use E6000 glue.

But this video shows how fun it can be to make a pair of shell shoes or flipflops for the beach. One note. If you buy a pair of inexpensive mesh shoes from Payless or Ross Dress For less her idea works even better. The less "stiff" the shoe is the better job the shells do staying on, so flexible fabric shoes work well. Or just create sandals. 

This craft idea works great with several of the products seashellsupply.com sells. We have a wide array of small bulk shells you can use. My favorite idea was to use tiny Zebra Nerite shells. Shell chips, like abalone chips, also work, as will rough seas glass, and you can also get a couple small colorful scallop shells, starfish, etc for accents. It's a great way to get some fun, dedicated "beach shoes" for the summer.
