Mom's second pair of purple socks were done, wrapped, and under her tree on Christmas Eve.
Once again I only did a five inch cuff for her and she says it's just right.
Multiple commenters with a better imagination than mine were quick to point out that the stitch pattern imitates wrapped candies.
It's so obvious now that I know. Thanks everyone.
While hunting for a BonBon picture on Google, I learned BonBon is French for "good, good", and is used for many different types of sweets and candy. The type of BonBon depicted by this stitch pattern is a sweet wrapped in paper twisted at one end or both ends.
I found the stitch pattern in Vogue Knitting Stitchionary 2. It's basically a knit 8, purl 3 rib. When stretched a little, the cables contract and pull in and the stockinette sections flair out giving a rich, wavy look to the pattern.
After being asked to share, I found a free version of the BonBon stitch pattern complete with words, chart, and clear picture here.
