thread source?

[savage_here]

I've been ordering waxed nylon bobbins from thethreadexchange in 277 and 415 sizes. I've found that I really need an "in-between" size. Does anybody know a source for waxed 346 in a variety of colors? Mostly what I use is white, off-white, beige, tan, brown and black.

If there's no source for waxed, any sources for quality unwaxed 346 would also be aprreciated. I'm not a thread expert, so bear with my not knowing the correct terms. But, I like the thread to be 3 strand with a twist.

Thanks all.
