Some years back I started working on a cardi of my own design. Had the back and sleeves done (for some reason I frogged the sleeves). Decided I'd resume this project when I ran across the back piece (along with a few notes on gauge but nothing to say what sz ndl I used).

I've worked up a few swatches in diff ndl szs that appear to be very close but nothing's an exact match (which, given the time elapsed, my tension at the time vs now, etc isn't surprising).
No plans to frog the back so any suggestions so I don't end up with fronts (yet to be designed) or sleeves that are waaaaay off?
BTW, the piece is worked in pillar st (pic in
this thread)
TIA,
