You can buy beadboard a number of ways. I know that Home Depot sells MDF panels of beadboard that are pre-primed, so you can cut them down to whatever size that best fits the banquette you are building. http://www.homedepot.com/h_d1/N-5yc1v/R-202075059/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053 Home Depot also sells panels of beadboard made from pine. Each package contains enough wood to cover14 sq. ft. of wall space. http://www.homedepot.com/h_d1/N-5yc1v/R-202075051/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053 You can also go the more traditional way with individual pine boards that interlock via lap joint. The individual planks from American Beadboard are 8" across when connected, and are cut at 38 1/8" tall. http://www.americanbeadboard.com/?gclid=CKGh6fXvxKYCFRRqgwodPRriIQ And beadboard wallpaper is gaining popularity as well. If it were my house though, I would go with the individual pine planks...but what can I say? I'm more of a traditionalist. How does everyone else feel about vinyl beadboard versus individual wood planks?
