For my last project, I made an arm knit infinity scarf. I used a video tutorial by TheCraftyGemini....I strongly suggest you check it out if you are interested. She does a really good job and uses slow mo for tricky parts.
This first one took me about 45 minutes but after making it I know it won't take that long next time. The trickiest part was casting on.
Wishing you all a Happy Crafting New Year!
