It's not about how many

The daughter of the Yarn Harlot answered my question: See "Excuse the seventh." Her daughter, Sam, apparently identified me as a knitter from a distance wearing grey bobbles, pink lace, and brown cables.

With my own lack of a hip-and-trendy teenager to query regularly, I seek out others who may be hip-and-trendy. I'll take Sam for now. My current projects in progress nor stash support her recommendation, but I'll take it under advisement.
