I just learned how to knit. But I can only knit rectangles. I don't know anyone else who knits, in real life. So I found videos online showing the cast on, knit, purl, and cast off. That's all I know how to do--so, it's all rectangles for me.
I prefer using the purl stitch because it goes much faster!
I have two pairs of needles, one long (over a foot long!) very skinny (5mm) metal needles which I hate. They are awful to use. And I have a short, fat pair of bamboo ones which I love, so I end up using them all the time.
My first project was a scarf for my 4 yr old little boy. He loves it and proudly wore it to school while it was cold. I have been trying to make rags now. And I found a pattern for a poncho that uses two rectangles. So I want to make one for my little boy for this winter. I think he would love it.
Let me join your club, please.
