Thanks Dice...I'll check those out! Those Chulaorchids ones look like they might work.
I did search google beforehand and found these:

I was thinking the 3 1/4 inch ones would work and they run a little less than 7 cents each. I'd have to use plastic plant markers though instead of writing on the cups like I usually do. Was wondering what other folks might use.
