This pattern is best if knit with any heavier yarn or yarn combination, like Aran, DK or Fingering held double. The heavier the yarn, the bigger the bag- a swatch will help if you want to figure out how wide your bag will be. To do this, make a swatch in stockinette stitch which is 32 st wide (it is helpful to frame your swatch with 2 garter stitches at each end.) Knit swatch until you have at least ten rows, then measure the distance between stitches 1-32. Multiply that number by 1.5. This will give you a good idea of the width of your bag.
