From the website:
Lynn Schneemeyer designed these neat twisted rib fingerless gloves using one skein of our Ultra fingering weight yarn. They are ideal for those in between days to keep your wrists and knuckles warm, but leave your fingers free to work (actually around our house, I’m thinking that they may be useful indoors all winter, given where my husband keeps the setting on the thermostat). Shown in two different handpaint variations of our Ultra yarn, you can knit them in any solid or handpaint colourway that you choose. In most cases a one-skein project. Also available as a kit, $14.
