I still have all my straights, but these days I knit mostly with my circs.
I'm in LUV

with my Denises (yes I

you too, foldedbird!), and use those whenever I can. Right now I'm using one pair of my straights for a sweater with the ribbing on Size 3. The body is on size 5, so I'll be able to switch to Denises when the ribbing is done. I WISH the Denises went smaller than 5.
I still use my dpns especially for size 0 to size 5 for socks, but for anything larger than that I'll use two circs from my Denises.
Happy Knitting :XX: :XX: (circ, straight or dpn!)
