Question on pattern

I would like to do this pattern to make survivor gifts for my relay for life this year and in the tools it says 4 DPNs I was wondering if I could do this on small diameter circular

No, it can’t be started on a circular needle because you only cast on 9 stitches and even though it ends with 72 after increases it’s not worth changing to do that even with a very small diameter circ. If you don’t want to use DPNs you can use Magic Loop or two circular needles of the same size. Magic Loop and two circular instructions are under advanced techniques in the video section. Both are easy techniques.

For the beginning yeah, a larger circ, like a 24-29" or use two of them.
