Take crochet plaid up a notch and make a crochet tartan hat! This new technique is only slightly different than the original plaid technique, but creates a whole new plaid look. By changing your color changes a bit you can create this tartan plaid effect.  
This hat has a cozy, stretchy, squishy brim that covers the ears for extra comfort!

This pattern is included in the Endless Bundle, learn more here.
