Knitting circles were once a popular place to exchange rumors about the area's handsomest fireman, which of the neighboring towns' mayors were secretly left-handed, and the fate of the Crumb brothers. Get your finger on the pulse and some yarn with today's Groupon: for $15, you get any two knitting classes at Far North Yarn Co. ($30 value).

Far North Yarn Co.'s skilled and seasoned instructors guide knitters of all ages through hands-on projects designed to accommodate all skill levels. A monthly schedule gets knitting needles clacking with classes instructing students on how to craft items such as a calorimetry headband ($30 value), whose elegant design both warms heads and prevents the escape of algebraic equations. A class on felted slippers equips knitters with the means to shuffle silently and stylishly, and students in the mock-cable-beanie class can tuck hair and ears into homemade comfort. Meanwhile, one-hour one-on-one private lessons ($15) give pupils individualized access to knitting senseis. All of Far North Yarn Co.'s classes require knitters to bring their own materials or buy them on-site. Material costs vary depending on class and style but can cost up to $60. The store’s wide inventory of yarns, tools, and books tempts hands with endless promises of knitted curios and houseboat cozies.
