From the designer’s website:

I am very pleased that this pattern was selected for the 1999 XRX book, Socks, Socks, Socks. It was substantially rewritten and improved by the editors for that book. This version is the original pattern.

These were designed for my 10-year-old niece Sheri, who says that socks with fold-over tops are for “little kids.” These have stand-up cuffs at anklet length.
