This was inspired by a diffrent instructable. If you havent seen it follow these steps:
Step 1: Materials
2) Wall putty
Step 2: Create the Disks
The disks sizes should be this:
1) Hour = Biggest
2) Minute = Medium
3) Second = Smallest
Step 3: Mark the Disks
Spin the discs around the clock to make the numbers. Repeat for every disk.
Step 4: Apply the Disks
Using wall putty apply the disks to the hands.
P.S.: If the hand still sticks out try making the disk(s) bigger or cover it up.
Step 5: Done!
Your all set! NOTE: If the clock has trouble take out the glass (had the same problem).
