Thanks to Jane, for her effort to come out with this SUPERB craft recycle idea for a "long lasting" clock that we can use to teach time to our kids.
CD, printed numbers (or maker), glue, thick protector sheet, card board, button and some sewing thread
1. Paste all the numbers on the plain surface of your CD
2. Paste a small piece of protector sheet (or thick cardboard)on both side of the hole in the middle.
3. Cut the short and long hands out of the protector sheet (or thick board). Sew both hands to the button, loosely for easy movement.
4. Sew them to the protector sheet on the CD.
