Heaven forbid you may, one day, find yourself in a situation where the last few projects you have done have all had Tension Issues. This sorry state of affairs may lead you to rethink your devil-may-care knitting attitude and actually, like, do a proper swatch for something.
Should this unfortunate set of circumstances ever arise, you might decide that you really are going to do what you're told this time, and wash and block the swatch.
If you do go to all this effort, it would be somewhat foolish to render it all useless by not actually bothering to wait till the swatch is dry before you measure it. This will lead you to panic, wonder why your gauge is so loose, and cast on a couple of sizes too small. It's only a day later while a stroke of incredible good fortune leads you to casually repurpose your swatch as a beer holder, that you may notice it has shrunk considerably. Wet things are bigger than dry things.
Ah well, back to the original size that I was going to cast on for anyway before I had this foolhardy swatching idea....
I suppose this whole sorry misadventure has at least given me this attractive beerholder though.
It may, or may not ever evolve into Eunny Jang's Deep V Argyle Vest. Maybe with a slightly shallower V. Having breastfed a baby for nearly a year now, I'm looking forward to putting my boobs away for a bit. Under some nice Rowan RYC Cashsoft DK.
