This process is a great way to recycle those old plastic bags into something useful. You can crochet or knit a cool tote bag similar to reusable totes that are sold.

• Cutting
Lay recycled bag out flat

Fold in half lengthwise then fold in half again

Cut off top handles

Cut bag in strips about 1 inch wide or as desired

Set aside the end of bag where bottom edge was glued. The ends and the handles can be recycled either as stuffing for other projects, packing material for shipping, or taken to your local recycling bin for plastic bags.

• Tying strips together
Take two strips and inter-twine together as shown

Gently pull on ends to knot two strips together

Connect next strip to last strip in the same manner

Continue connecting strips until you have a large ball of plastic “yarn”

Tips:
Pull ends evenly to create a smooth and flat strip.
If you find your strip doesn’t lie flat between knots, you didn’t pull
evenly which creates a bunched strip. Just make sure your strip is
even before you pull your knot tight between the two connected
strips. To fix a bunched strip, just loosen your knot between the strips
then pull on the ends again to make your strip flat and smooth.[…]
