The lovely Imbrium asked in a comment if the sock I’m working on is snugger than usual due to the twistiness of many of its stitches. It is indeed.
That is why I work the top (instep) of the sock on a 2.5mm needle while the bottom (the sole) is on my usual 2mm needle. After the turning of the heel, when I continue the pattern around the back of the sock, I work both halves of the sock on the 2.5mm needle.
To do this, you really do kinda sorta have to knit your sock on two circulars. You can’t do two different needle sizes if you are magic-looping (duh), and while you could conceivably do so with dpns, you’d have one heckuva time keeping track of which needles were which, unless your two sets were of wildly different color or composition. Even if this were the case, I know I’d screw up because I get myself into a sort of fugue state when I knit socks and stop paying attention much of the time.
Making this sort of adjustment is helped along by the great range of sizes available in the Knitpicks needles. In the fixed-length circular (which is what I use for all my socks) you can get 2mm, 2.25mm, 2.5mm, 2.75mm, 3mm, 3.25mm, 3.5mm, 3.75mm. Well, more sizes, but this is the range I use for knitting socks. Holy tiny increments, Batman! Gotta love it.
Of course, if you are a die-hard dpn user (cough::L-B::cough) you could simply knit the entire sock on a needle one size larger than you would usually use. For example, if you usually use a 2mm needle, use a 2.25mm needle all around. But I like keeping the sole and heel on the 2mm and going up two increments for the patterned bits.
Here is the first Costa sock, completed.
I am very pleased with it.
