To make your own bags for free, all you have to do is the following:
1. Get a tshirt. It does not have to be big. The ones I used were a ladies medium and made a reasonable size bag.
Feel free to use one without a cat on it. In my house it is rather difficult to fine such a shirt.
2. Turn the shirt inside out and pin the bottom edge together.
3. Sew the bottom together. Remove pins.
Yes, that is a very old sewing machine. Call it my version of environmentalism. I use this one and it stays out of the landfill. Also, it is the only machine I have!
4. Cut the sleeves off. I did not cut through both sides of the sleeve at once after the first bag, the handle turned out a little thinner than I would have liked. I cut around the armhole through one thickness of fabric at a time after that. Worked out better.
5. Cut straight down beside the neckhole on both sides and then across to make a square opening. This I did through both thicknesses of fabric at once.
6. the bag is done!
7. Repeat as many times as you have t-shirts or patience. All 4 bags took me less than an hour.

Happy cheap recycling!
