Potato bag, "This bag is a bag you put your potatoes in, throw it (or place it) in the microwave, heat, and the end result is super fluffy, soft, baked potatoes. I mean like awesome...and to make one is super easy."
By making 2 marks on the side of your thumb, and moving your thumb along as you work, you have a built in gauge for exact stitch length, without marking up your fabric. Genius, right? PLEASE NOTE: THIS IS NOT MY THUMB NOR MY IDEA. This anonymous thumb is perhaps the most intelligent thumb in all of history.
So easy to sew ~ It's just 4 rectangles. Measure shoulder to hem length, then girth at widest part and divide by 4. Add seam allowance. Sew allowing for neckline, arm holes. No pattern needed. 1/2 hour, max!
