Oh I think this is utterly SUBLIME! I really love it! You chose a wonderful yarn, and color...and the pattern stitch shows off the yarn and colorway so nicely! I'd never know you had any boo-boos!
I know whatcha mean about mistakes in a pattern stitch like this. Oh boy, do I ever! And I don't know if a lifeline would really help much...but I'd try to figure out a way to use one, that's for sure.
Anyway, I had to laff at your humor...."repeat to infinity and beyond..." he he That struck my funny bone!
It's a great knitted work of art! Be proud!
