I just finished making a huge 4" X 6' bulletin board for my art studio. It's more of an inspiration board, because I put all sorts of meaningful things on it, like photos of my grandkids and art awards. I knew I wanted to put something on the wall by my drafting table - a wall I look at every day. Then I stumbled on a tutorial about making a bulletin board out of Homosote, which is a brand name for pressed paper board. It's 1/2" thick and comes in sheets of 4' X 8". I found it at a local lumber yard & it cost about $30. Here's the directions to make your own art inspiration board
I found green/blue patterned material at Wallmart. It's jersey, so it stretches & doesn't show wrinkles. I stapled it on the back (added some duct tape, too) & hung it by knocking nails through the board into the wall. Push pins hold my papers. Now I'm inspired to work on art!
