nothing bigger than a#5 set of needles. The smaller the better for colorwork.

My current favorite hook size is probably a 4.25mm or 5mm! I like to use a variety of yarns and I feel that these sizes are fairly versatile(not to mention that those hooks are fairly sleek and don’t have any handle/cushion/grip thing
)

I work a lot with the 1.9mm, 4.5mm, and 12mm.
I use/experiment with all yarns/threads. The only one I can’t use is wool. I’m allergic to wool.
