Last year when I ordered postcards for the Sawdust Art Festival to hand out I received 1000 printed with markings and margins...ugh! These were then replaced by the company, but what to do with the ones made in error? I used many as "identifiers" on back of work, but still there were sooooo many remaining. Just sat down with them last night and turned the ends into business cards. Why not? There seems never a reason to toss things if only you turn on your imagination!
