This is so wonderful to find! I make seashell chimes as well! I used 2 CDs that were all scratched up (also save those free AOL ones that come in the mail!) glued them together, drilled holes where I wanted my shells to hang, then spray painted the CDs, glued shells and beads, sand and sea glass on them and proceeded to string my shells. I found that a dremel works great for smaller shells, but for larger, thicker shells, I used a masonary bit used for drilling cement! I also use beads for a filler on the strings! Here is one! thank you for sharing all these!
