Recycled T-Shirts

I found this cool instructable for using old t-shirts to make grocery bags. I wish I had a few of these when I went to Wal-Mart tonight and walked out with 50 plastic bags: one for each item I bought. Does each head of lettuce really need its own bag? Could we possibly put two dozen eggs in one bag? How about the bread and the english muffins in one? No? Ok. Next time I'll bring my old t-shirts.
