Today's stitches will be
double knitting and Tunisian simple stitch
This is a style of knitting that creates a bag that is closed on the sides and the bottom. The bag may or may not be able to be used as a bag depending on the techniques used to knit.
Any number of stitches.
Cast on half the number of stitches needed for your project. For mine, I will cast on 16 stitches. Use smaller needles since the stitches will grow a bit. Use a long tail cast on.

Rep R2 until you have a square.
Tunisian Simple Stitch
This is also known as shepherd's knitting and Afghan Stitch, among others. It uses a long crochet hook, called a Tunisian Crochet Hook. Use a hook larger than you normally would with a regular hook. This can become very tight and feel like cardboard if you don't.
Ch the number of stitches you need for your project.
