Ok so, I heard about these from my sister, did some looking online and then made these for a couple hospital worker friends and family. The idea is: home you come - work clothes in the bag, bag and all in the washing machine.
They are about 21"x21"'
They are super easy - and the drawstring is already in there and you don't have to cinch it through with a pin! - Hooray!
Enjoy the easy "pattern" and instructions and straight line sewing!
And no - these are not the best instructions or diagrams or video ever - but I am rather proud of myself for sending it out without it being perfect!
