Tutorial : Plastic Bag Knitting

Lay the bag out still pleated:

Cut off the handles and the bottom (if you don’t cut off too much a target bag will yield 18”):

Unfold pleats and lay flat:

Now mark 3” from one folded edge:

Fold the bag over to meet that 3” mark:

Now fold again to the 3” mark:

Across the folded section, mark 3” intervals.

Now cut only through the folded section at those 3” marks:

Draw lines that begin on the left side of each 3” section and end at the top 1.5” over to the right:

Fold the top over and continue each line over the top and to the right until it meets the slit to the right of the 3” section:

Finished lines:

Now cut on those lines through only one layer:
