I have had plastic grocery bags waiting to be processed into plarn (plastic yarn) for … well, let’s just say it has been awhile.

The technique I have been using involves folding and cutting one bag at a time, which is why they have languished on the hook, waiting. I decided to try a different method, using a cutting board and a rotary wheel. I pull each bag flat, which easiest by finding the bottom corner and pulling on the handle, and stack it on the cutting board. Pictured is a stack of five bags. I then used a ruler that is one inch wide and my rotary cutter to cut off the sealed bottom.

I continue up the bags, cutting one inch strips using the ruler, until I reach the handles. This gives me approximately 60 plastic loops for 13 passes of the cutter. I do discard the bottom and top of the bag. I have cut up to seven bags at the same time comfortably, and could probably go higher, when I’m feeling brave.

It is definitely worth getting out the cutting board and rotary cutter to process bags, this goes so much faster than with scissors. The loops are more consistent as well, using the ruler, than eyeballing the angle with scissors.
