Make a scrabble tile keychain with your name’s capital letter!
This is easy. You need a scrabble tile, a key ring, a loop screw and E-6000 glue. Now screw the loop screw into the tile, to make the hole. Add glue to the loop screw before inserting it again. Then attach the key ring and your key. Be sure to have a small enough loop screw or the tile will crack.
You can also make an other variant of this keychain by drilling a hole in the corner of the tile and attaching a small key ring. For more ideas check out here.
