I think bc I only have 3 coworkers, it would be REALLY obvious if I didn't give to one of them but to the others. or if I gave to my friends in the firm, but not them. I figure 3 is fine. I can do all 3. I make it look really professional like it was a gift box. In fact one year my boss asked me where I got them and I said I made them and she was surprised bc "it looked so professional"
