Do you all know the plastic corrugated boards that people put on those wire (stick in the ground) stands? Around here, some folks advertise their yard sales on them or if they are running for local office, they are pre-printed. I collect them when elections/yard sales are done and cut them into boards, 6 x 9, to wrap all my fabric. I've got quite a stash of them waiting for my fabric stash to catch up!! Cost? ZERO!!
