Flat Knitting

From KnitWiki

Flat knitting produces flat fabrics starting at one edge and working towards the opposite edge (double knitting is an exception).

When knitting flat you turn the work at the end of a row and start knitting back in the opposite direction. A good simple example of flat knitting is stockinette stitch.

Flat knitting is often worked on straight needles, though larger pieces are easier to work on circular needles.
