I've been carding the supplement to the fabulous-but-limited roving.
The largest bump is the original roving. Below it are two items I pulled from stash that I have been carding together to produce rovings like the two smaller ones. One has an outer layer of purple, the other of red, but both are a mix of approximately one part purple to two parts red.
You can see that the original roving is much brighter. My plan is to spin the two rovings (old & new) separately and ply them together. That will give me about 24 ounces of sportweight yarn.
But is the new roving too dull? I am about halfway through carding, and I don't want to recard & get it too blended -- this is one pass through the supercarder and I think another pass would give me very bland results. I could make another thin roving, though, and hold it together with the new roving while spinning. Hmmm. Or maybe this is just fine as it is.
I think a few more samples are in order.
