Infinity loop and coordinating headband.

Infinity Cowl:
Chain 151. Beginning in 2nd chain from the hook, hdc across in each chain. Every following row: chain 1, hdc across in the third loop (the extra loop created behind the front and back loop with an hdc) on the right side this will be behind the normal stitch, on the wrong side it will be in front of it.

Ear warmer:
As this yarn was a bit heavier than called for in the pattern I started and finished with 5 stitches instead of 7 and did fewer increases/decreases overall - maximum stitch count of 18 - and did a few extra non-increase/decrease rows to make up additional length.
