After learning several ways to create form out of fabric, I wanted to explore different kinds of textured  knit fabric. I generated several swatches, each 15 stitches wide (but varied in how many rows). Most used a long tail cast on (learned here) or a knitted cast on, and all of them used a k1k2tog cast off. I settled on these cast ones/bind offs because they are stretchy and were easy for me to learn. I thought that using a stretchy cast on/cast off would be best, since the tight cast on/cast off in most of the beginner tutorials I found would distort the textures I wanted to create. I used the same yarn and needles for each sample, so that different needle sizes wouldn't affect the samples.
