Here's my version of Ana's 'Numbered Cubbies on the Wall'. Mine is made from a 6' long 1/2" x 3" craft board and a 6' long 1" x 4". I followed Ana's plan, adjusting mine for a smaller size and proportion. I used a finish nailer with 1" nails. The numbers were drawn on with black Sharpie following Ana's method. First print out a 3" number in your choice of font, cut it out and tape to the cubby, press HARD to outline the number with a ball-point pen, then remove the stencil and fill in with paint or marker.
This is an easy and fun project. It's very versatile and cute and looks store bought and expensive.
