Hey welcome back! You've been missed!
A sock-knitter friend of mine keeps a perpetual sock gauge swatch on the dpns so now she has a long tube of swatches connected together. Most of her yarns are the same weight, so the same needles, give or take a size, work for her. YMMV
I plan to start my own sock tube swatch once I get the right size dpns. It's kind of neat to see all the past socks she's done in one tube. I guess she can afford to have the extra set of needles. Supposedly you want to swatch in the round if your project is to be done in the round.
