I feel your pain and commiserate!
I got 3 inches into a placemat knit in crochet thread, when everything went kerblooey! My mind couldn't follow the chart and then I knit into my lifeline, and it went downhill from there trying to fix the damage. I made such a mess of it that I ripped the whole thing out. At least I can still start it over, or so I think. I could be mistaken on that count.
It's a lovely pattern you're working on, and I'm sure you'll get the knack ASAP!
