Schachenmayr has combined two of their most popular Regia self-patterning collections into one grand option- a Pairfect collection designed by Arne & Carlos!
Perhaps you've knit the Pairfect collection before. It's the one that gives you two perfectly matching socks by having a thin yellow strand at the beginning and middle of the ball that indicates where to start for each sock. And perhaps you've also knit some of the Arne & Carlos colors (they even come in heavier weight)- these are the guys who design the popular Norwegian sweaters and translated that work into self-patterning Regia socks.
Well, now the two concepts are one and you can get two "pairfectly" matching Arne & Carlos socks!
Are you a person who wants two matching socks? I'm well documented as being on the "oh, forget that" end of the spectrum. But a balls that's over 450 yards is plenty for my size 11 feet, even if I'm wasting a bit to get to the middle part to start again. And the colors and patterns are so cool that I really feel the need to cast on.
