I was in Joann's last week and the lady in front of me had a bolt of terry cloth. We got to talking about what our projects were and she said she was making lettuce bags for her family for Christmas. I had never heard of one. I never got more info from her. I have a devil of a time keeping lettuce fresh in the frig and she said these bags keep lettuce fresh for a long time. Does anyone know about this? Measurements and instructions? I don't know whether you put them in frig dry or maybe damp. Appreciate any information anyone can give me.
