I love old aluminum needles - though I prefer Boye to Bates! Something about the old-school buttons… apart from the comforting aesthetic, the buttons hold knitting on the needles much better than the new style ends on the Bates. I prefer knitting my sweaters on Boye aluminums over knitting them on circs.
I also love wooden needles - birch dpns and long straights. I became a fan of the Brittany line thanks to a fellow historical reenactor.
My latest source of joy has been circs - my love for Addis has given way to love for Options, because they not only perform well, they take up less space! That being said, I have three projects on Boye needles, and only two on circs! Circs serve me well for shawls.
