Make from plastic shopping bags.
Then you can use it to create something like the purse that I crocheted out of Plarn,
You will need:
*Plastic shopping bags
Step 1: Flatten Out Bag
flatten out the bag by pulling at both ends.
Step 2: Cut Top and Bottom Off of Bag
Then cut the bottom seam off of the bag in a straight line.
Step 3: Fold the Bag Lengthwise
Step 4: Fold the Strip
Step 5: Cut in Half
Step 6: Cut Strips in Thirds
Step 7: Open Strips and Attach Together
Take two strips and loop them inside each other.
Pull each end until there is only a small knot.
Then keep attaching one loop at a time to the end
until you have a ball of yarn.
If the bag has a hole, that's okay. Or if the loop is not closed.
Just tie a knot so your plarn doesn't come apart.
