Here’s how to fold a bin liner/garbage bag out of spreads from a newspaper. It’s adapted from an origami technique, so it starts out with a square. You can cut the extra bit to adjust the format, but I prefer the following, which makes for a bigger bag: Use 4 sheets. Lay down the 1st one, then the 2nd, sliding the latter up until the overall shape is a square. Place #3 over #1, and #4 over #2, to increase your square’s thickness and cohesion. Then proceed to fold.
