Here's a little tutorial I've put together on how I make plarn.
- Plastic Grocery Shopping Bags
- Scissors or Rotary Cutter
- Yard Stick (Not necessary, especially if you have a good eye at keeping cuts straight)
- Cutting mat (Only if you're using a rotary cutter. Although, unless you have a dedicated crafting table, using a cutting mat will protect your furniture.)
Step 1: Open up and smooth out the plastic bag.
Step 2: Trim off the handles and the bottom seal.
Step 3: Open up the bag, releasing all the folds. Flatten and fold vertically to a width that you are comfortable cutting. I fold until the piece is about 4 inches in width.
Step 4: Cut bag across into 1-inch strips. (A standard-sized shopping bag should produce about 11 or 12 1-inch strips)
Step 5: Open up the strip and chain the strips together.
Process as many bags as you wish. One standard sized plastic bag yields about of 5 1/2 yards. Once you've made your desired quantity, simply roll the plastic yarn into a ball. Sometimes I get lazy or too excited to chain all the loops before I start a project so I just chain the loops as I go along with my project.
This can be used on any knitting or crochet project that requires a chunky weight yarn.
