This bag is designed in using modular garter stitch: a divided square, which is a technique described in detail in the book “Number Knitting,” by Virginia Woods Bellamy.

The bag is seamless, and works up quickly. I was able to get four bags out of a 236 yard skein of yarn.

These bags are great to put in shoeboxes for Operation Christmas Child. Work them up in a variety of colors, for both boys and girls.

If you want a bigger bag, just cast on more stitches. If you use solid colored yarn, make the bag more interesting by using a fluffy or sparkly yarn for the shell stitches at the top.
