This came out pretty well considering! I have started and frogged the front 4 times before finally getting it mostly right.

Learned that while knitting the punch card fair isle, the carriage must pass the card fully and clear all needles, each pass. Sooo if you are knitting a vest like this, you can’t just place part of the work on hold, because it probably won’t be close enough to the card for the carriage to read its next row. Also when you go to the second side, you have to reinitialise the pattern in the right row.

So the way I did it was to scrap off at the armpit, then rehung just the stitches I wanted. They have to be hung with the same position relative to the little marks on the marker tape stuff (with numbers) or it will be out of register with the repeats of the pattern.

Keep in mind that the card reader needs to be there but you risk not passing the row counter!

So decreasing neck and armhole edge at the same time and picking up the inevitable dropped edge stitches and THEN going to the other side and repicking up in the right place and starting from the right row of the card- not forgetting to do a free pass first to ‘memorise’ the new sequence!

well I got it mostly right and I am super proud. There is a small patterning glitch which I will fix with duplicate stitch but it wasn’t near the start of the section so I think I may have not passed the card reader properly on one row?
