I have seen these blocks around for about 8 years now, and even made a small set for a Super Saturday about that long ago. But I was re-inspired to make a new set after seeing Stephanie's. And then, Shannon decided to make a large set for her family and it got my wheels spinning even more. Here are some step-by-step pics to help.
I had these chip board letters lying around that I got from the Target $ bins. I spray painted them all red.
Number your 15 blocks 1-15 on the bottom.
I painted mine a latte' color and then
distressed the edges with brown paint
I laid out the letters on each block according to the cheat sheet I have (I can get you a copy if requested)
and then I decorated away. All the other versions I have seen were just letters stamped on the wood, but I wanted it to be more of a vocal point on my mantle, so I added a little flair.
