I should have seen it sooner; that my poor sweater back was falling victim to that old baddie GAUGE. The classic symptoms of denial were present: tugging at the length, stretching out the bottom edge and telling myself it would relax with a good blocking. Then I woke up and decided to face the truth.
First I laid it out and gave it a steamy once over to relax it just a bit. Then I grabbed my measuring tape and assessed the damage. My sweater back was measuring 14″ wide and the schematic was telling me it should be more like 20″.
In my defense, I did do a gauge swatch. But it was pretty teensy, and it was in stockinette, which is how the pattern gauge was given. I think I would have been better off swatching in the cable pattern so I could account for how much the cables pull in on the overall fabric. I think the only positive I can pull outta this one is that now I have a really big gauge swatch. Off I go to start over again and mark this one a big fail.
