This project is moderately difficult and is fun and pretty easy.
Miter box and Saw
An orbital Sander
2x2 Pine post.
Measure out the wood and mark it. In this case the high and the width of the wood was 1 1/4 inches... So i measured out 1 1/4 inches in length out of the post.
Now use a miter box to cut a strait line. But you must compensate for the kirf of the blade but cutting next to the line that you drew on the wood.
This is how it should look after you are done. Also do steps 1-2 again to make another cube.
Step 4: Sanding
Use an orbital sander to round out the the cubes.
Then use a sharpie to make the numbers and marks on the cubes.
Step 6: Optional
Then stain and wipe of the excesses stain. OR. You could use linseed oil.
