Thank you everyone for your positive response on the socks. M-H writes "Er, Duffy, I don't think that age has anything to do with the brightness of your socks! I wear bright coloured socks all the time, and I'm quite a bit older than you." You're right. It's not age. I figured out what it is about the multi-dyed sock yarns that I don't like and it's the striping that the yarns do. (I have short wide feet and chunky ankles) When broken up with a different yarn, though, they give an appearance that I like.
As for a pattern, I'm working on that. The trick is that with a motif like this it's not easy to set it up for different foot sizes. I thought that working the motif twice would be the right size for my foot before starting the heel but I found that not to be the case. I also have to figure out what I need to do for my high instep and the leg. So I'll be looking at different motifs so that the pattern can be written up for several foot sizes.
