Steve Spangler and all over Pinterest.
In order to get through 40 kids in an hour, we set up a table to rotate the kids through - it worked out pretty well. Most tutorials I looked at used cups to stretch the fabric, we used 6
inch embroidery hoops since we have a lot. Each sewer was given a
pre-cut piece of white muslin - ours are 7-1/2 x 15 so that the hoops would
fit on them. There is a hoop on each end of the fabric so that the bags will have a different design on each side.
