So my big news is that Catherine at Catherine Knits in Brooklyn just got in her yearly shipment of Holtz & Stein this morning. They have arrived: sizes are from 2.5mm through 4.0 in rosewoods, including 3.25 and 3.75. DPNs are in the same range.

Note: I have ordered from Catherine twice now, and it was a delight both times. The order arrived well packaged and quickly after I placed the order. Though she warned me this morning she is swamped.
