A pidge is a short scarf that buttons at the bottom. The very fashionable (and seemingly, desirable) pidge sells for something like $325 on the website linked above in Newbie2Knitting's post.
Most knitters who see it shudder that anyone would pay that kind of money for a scarf when they could hand knit one very close to the real thing for much cheaper. I'm attempting my own version from this pattern out of Debbie Bliss Pure Cashmere that I got on sale at LittleKnits.com for a mere $8.99 a skein. My attempt at the Pidge will probably take about 4 or 5 skeins and cost me a whopping $45 plus buttons.
The real mystique about the pidge for a while was how to recreate the stitch pattern. I think someone figured out was done on a knitting loom as opposed to needles. There was a group devoted to deciphering the pattern and recreating the pidge on their own on Ravelry. If you are interested and search the Ravelry groups for "Smidge" you will find it there.
Oh, and IMO, for a pidge, I'd go for the twisted Moss stitch.
