Use For Old Business Cards

Well, now that I am retired, I have 2 whole boxes of cards, but knew I could find a use for them instead of throwing them in the trash. After reading about lots of uses, such as notecards, which is OK for a few, I found instructions to make cubes from Sam Allen of Zeta. Since my husband is still working at the company, I will attempt to make a huge "B" constructed from cubes and set it in the company lobby.
