I searched the net for salad bags..I found 2 that are manufactered..One is made of microfiber and the other is 100% cotton..they have a drawstringtop and are about 7x9 inches in size..Looks promising..I may give it a try..Just wash your greens and put in bag while wet..It keeps for 2 weeks..Then just wash the bag in the laundry as needed...
