This large family rules board I made for a friends home, is 2 feet tall by 3 feet wide. It is made on MDF and first I painted it white. Then put on a vinyl stencil, painted the lettering black, then pulled the vinyl off when it was dry. Then I sanded the edges, and took stain and rubbed it around the edges and a bit across the top.
This pallet is 24" tall by 30" wide. I built the pallet of 1x4x30's and then stained them all. I cut the stencil out of vinyl and painted the heart yellow. When that was dry I added the love in turquoise on top.
