Preparing The Back to School Clock
I bought the clock at Walmart for less than $4. You need to remove the screws from the back and take the clock apart. Remove the hands and set them aside but be careful. Remember what order they came off so that you can put them back on the same way. They bend easily.
Measure the diameter of the clock. That is the distance from one side to the other across the center peg. Subtract a little (0.1 inch or so) to make sure it fits and this is how big to make your clock face. The Walmart clock measured 7.25 inches and I cut the face at 7.2 inches.
