You will need:
Plastic bags (you will use TONS of them)
Crochet Hook (the size depends on the project)
Step 1: Cutting the Bags
First, take a bag and lay it out flat. Cut off the bottom edge.
Spread the bag out flat, getting rid of the wrinkles and making sure the sides are straight.
Fold the bag until it's in a strip a few inches wide.
Cut across the strip every half inch or so until you reach the handle area.
Step 2: Knotting Together
Take two strips and unfold them.
Take the right strip and loop it through the left one.
Take one end of the right strip and pull it through it's other end.
Pull and ensure both sides are even so the strips don't tear.
Tighten into a small knot.
Step 3: What You Can Do!!
Crochet as you usually would with normal yarn, and the possibilities are endless!
This produces incredibly durable pieces. I've only made bags so far, but my next project is a bikini! I'll post pictures when I'm done!
