I'm 2/3 done. Ish. Just the top chunk left. I'll probably hit a year working on it before I finish but it'll be close.
Are you using DMC 310 for the black? Try using 4 ply instead of 2 (and a laying tool) for better coverage, or use my trick and sub in DMC 939 for black. DMC 939 is a very, very dark blue that is almost black. For some reason, DMC 310 is super thin and doesn't give great coverage.
