I have only used size 28, and 30. I am new at crochet with wire and beads, but I find the smaller the wire the easier to get more even stiches. Now, I have never made a rope, only multiple strands put together. Good luck, Patti
I came back, as I didn't tell you the hook sizes I have used. H/8-5.00MM _I 9/-5.50MM
