The last two bags were good, but my ultimate goal was to make a bag out of plastic and seal the seams with more plastic bags all a string to the top and make a 100% waterproof bag. So to make this bag I did the following steps.
1. Lay a bag down flat and cut the bottom and handles off.
2. Cut up the length giveing you a sheet of plastic.
3. Do this 4 times.
4. Lay down a sheet of wax paper.
5. Pile the plastic bags on the wax paper. They dont need to all fit on the wax paper I had to lay it down iron it and move it 4 times.
6. Lay the second piece of wax paper on top of the sheet of plastic.
7. Iron the sheets together and more it forword and reiron. Your iron should be set just hotter then silk.
8. Fold the sheet in half and sew it the the edges.
9. Iron a second piece of plastic over the seams sealing the bag.
10. Sew a string along on side of the top of the bag.
11. Fill the bag with junk.
12. Roll the flap down and tie closed.
Your bag is now 97% waterproof!!!
