The first one was eaten by moths, and on the second, I realized that I had done every single wrong side decrease backwards after 221 rows.

This picture was taken when I finished chart 3/6, which puts it at 300/554 rows complete. This is easily the most complex lace pattern I've ever done. There are 18 total pages of charts (each one spans three pages), the ring lace background is garter, with no rest (knit/purl only) rows, and every single row is different.

Edit: Just realized I forgot to link the pattern.
