To save $32, I handmade a US 50/25mm circular needle using these directions:

1. inspirationrealisation.com/2012/11/diy-giant-circular-knitting-needle.html
2. knittersreview.com/article_how_to.asp?article=/review/profile/061109_a.asp

SUPER helpful for when I’m missing certain needle sizes or wanna make circulars that are sized for gloves. I spent a total of $4. 1” birch dowel was $3, and the electrical wire was $1, while the rest of the products I already owned.
