Yarn > Brand > Ancient Arts > Meow and Woof Collection Ancient Arts has produced a sock/fingering weight yarn that takes it's colorways from the coats of our favorite canines and felines. It is known as a "cause" yarn, because a portion of each sales goes toward homeless pets in the US and Canada. Knit something that reminds you of a former pet or your current companion. Each skein contains 372 yds/340m of 3ply fingering/sock yarn made of 80% Superwash Merino and 20% Nylon. Knits to 7-8 inches on a 2.50mm needle.
