This listing is for a digital PDF download of the Altitude Hat knitting pattern. There was once a jolly happy mountain that offered fantastic advice to a grumpy hill. "Change your altitude", he said! (I totally swiped that from the internet, but it's true!) The Altitude Cowl will keep your interest peaked as you climb the purl hills and navigate the knit valleys in your chosen rainbow of colors. This should summit up nicely: the Altitude Cowl is a fun, fully-customizable pattern written in both single-sided and infinity versions in either DK weight or worsted weight yarn. This may just be the last cowl you Everest need to make! (Kidding. Please make more cowls, they're the best.) This pattern is meant to be extremely customizable, but there is a little math involved. Please read through all front-end instructions if you plan on making a custom piece! If sharing your progress and finished piece on Instagram or other social networks, please use the hashtag #AltitudeHat so I can admire your beautiful work! Happy knitting, friend!
