Volunteer interior designers made these cork boards for us! They repainted picture frames from the store and used old wine corks of different length to create a fun and funky texture. www.habitatgsf.org/restore
Looking for a backsplash with a little more spice? Try what sunnyvmd2b did, and go the DIY route. Just know there's quite a bit of work involved. Instead of opting for the standard tile, this Houzz user used a combination of collected and purchased corks (about 650 in total), and painstakingly cut them in half and adhered the flat side to the wall.
