Well here's just the thing, a seashell wind chime. I made it in just in hour or two, with things I already had. Have fun!
Step 1: Gather tools and materials
Get more shell than you think you will need, because you will probably brake a few.
Step 2: Put holes in shells
Make hole in your other shells. I used about 50 shells.
Step 3: Thread on the shells
Make 5 strings of shells, one a little longer than the rest.
Step 5: Finish
Hope you enjoy your mobile!
