Steve and Carol -- you've both got great suggestions. If I can get the labels down to 10 cents each, that will be affordable on my budget! I see a trip to Staples or Office Depot in my near future. Carol, thanks for the tip on the laser printers and the software. I've got an ink-jet right now, but I think that the labels might get damp, especially if the clamshells are in the cooler, so I'll look into a Brother B&W model.
Steve - I'm trying to stay busy until I can start tomato season again!
Thanks much!
Lyn
