Q&A for How to Create Seashell Wind Chimes

No, but oiling them will keep them shiny and strong.

Wire does not sway or move like string does, so if you want the shells to move in the wind you shouldn't use wire. But if you just want something to hang shells on, wire is a good choice.

You can use a drill to make a small hole in the shells.

Use a cloth to wipe away the cobwebs and use water and a sponge to clean away the dust.

Put the larger shells on the bottom because the large shells are heavier than little shells.

Just take the string and make a loop under the shell, pull the rest of the extra string through the loop and pull. Keep doing this until the knot is bigger than the hole in the shells.

You can use whatever size you want. Just be cautious, because the smaller ones tend to be sharp.
