Sweater Weather

"If you’re wearing a knit shirt right now, you already have a great learning prop handy. Preferably, it would be a sweater because the coarser the fabric, the easier the knit stitches will be to see. So, if you’re looking down at your shirt now, you can see on the outside that the fabric consists of columns of many little Vs of thread or yarn. Now look at the backside of the fabric – the inside of your shirt. You’ll notice there are many little bumps instead of Vs. You’re looking at the effect of knitting and purling."
