Whoa. This is super impressive!! I was already pretty amazed by your Power Girl getup, which is awesome by the way, and then I saw you also did Big Barda before. WOW. Didn't it take ages to make?
I think the whole costume took a couple of months, working pretty much every night on it. The hardest part was the helmet. It's three tiers of black yarn, the basic yellow trim, enlarging the yellow triangle, the red bit, the medallion, the two helmet stripes, and then the sticky-out helmet detail. I kept thinking I was finished and then realized I needed to add something else on.
The cape was the easiest because it's just triple crochet (same as the PG cape), and the only real time-suck otherwise was all the crocodile stitch I needed for the scales. So many crocodile stitches.
