The Wholecloth Bento Bag PDF sewing pattern comes with 4 sizes of print-at-home PDF pattern, and clear illustrated instructions for creating the simple origami style project bag out of a single piece of cloth. This is a beginner-friendly project, and a quick sew!
This infinitely versatile bag is a popular way to tote your knitting project, or organize several WIPs. It's also great for storing finished sweaters, organizing small items together in your purse or suitcase, or keeping diapers and wipes close at hand. The smaller sizes are great for carrying your lunch or snack.
