My guild makes the bag Bellaboo posted the pattern pic of.
It is fast to make and holds many quilts. Perfect to hold all the sewing things needed for a class or sew day, plus several quilts. All you need is big square of fabric and two dowel rods. We use upholstery or pre quilted fabric. The bags are the first to sell out at our Sale Table at local events. My son in law uses one made with canvas for bringing in firewood.
