I've seen this concept all over the internet and I finally had an excuse to make a set for my sister's baby. The wood is beautiful straight grain fir that used to be a two by four in my neighbor's house. The nail holes are still there which is kinda cool. Mr. H and I cut up the 2x4 into ~1.5" cubes sanded and painted. Biscuit potato printed the fabric I stitched up into a canvas bag.
