I'm looking forward to trying all the brands recommended in the comments, especially Simply Socks' solid color line - I just love those colors. It looks like I can now find solid sock yarn in any colors I want. Also, I have decided not to try to use Baby Ull for socks as it does sound like the yarn won't wear well - thanks for that advice as well.
I finished some orange socks - first a pair of socks to wear while one of my favorite teams the San Francisco Giants are playing. I bought some Knit Picks' Stroll Hand-Painted yarn in theTiger colorway because it kind of reminded me of the team colors. Then I tried to use it for a stranded star pattern which wasn't really a success so I just did boring checks. Perhaps they will prove good luck to the team though if I wear them when they are playing. (BTW, if you look up "Baseball Socks" on Ravelry, Meredith Wills has a wonderful free pattern with charted out logos for all the MLB teams. There are several different versions of the pattern depending on the teams.)
And also in the orange theme I made some thick socks. I have wanted to use up this orange Kroy for years so I doubled the yarn for these socks and used size 4 (US) dpns. I used almost three skeins so I consider these socks more of a success.
Oops - I put the original chart in backwards - here it is for working a top down 72 st chart. Thank you Marcia for noticing this!
