I even done a custom style one in that the lady has badly swollen legs so the rib no matter how large a size or loose i did the rib still wasn't enough
So came up with the idea if instead of doing on the round using DPs i did the rib on straight needles still using a larger size then when rib done change to DPs then knit on the round as normal so there is an opening on the rib the lady said they were perfect
All the socks are done in 4 ply yarn
