SOHMO Project Envelopes are the perfect way to keep track of all of your WIPs. Keep swatches of fabric, thread and trim in the envelope, and record the details of anything you'll need to pick up next time you're at the fabric store. No more over-buying fabric (ha!) because you can't remember how many metres/yards a pattern needs. 10 envelopes per pack. Envelope size: 120mm x 160mm
