Its really very easy. I went to HD, bought a piece of precut square ?particle? board. Put several coats of white primer on it. Drew my quilt block on graph paper to scale, then transferred the pattern to the wood with a yardstick and pencil. I used blue painter's tape to tape off one section at a time, painted it, and let it dry for several hours. (the hardest part was waiting!) Easy peasy. You can google images of barn quilts for inspiration. There is a picture of mine on the picture board, along with several others from these talented artists! Have fun! I am letting my block "weather' this year, and will let it get nice and dry in the basement this winter, then seal it.
