I thought about swatching and then throwing it in the washer and drier to get the gauge, but I was too lazy as I don't own a washing machine and use wash and fold services.
The yarn may very well go back to the original gauge after it goes through the drier.
I'm sure you know this already, but I thought I'd share my experience with the 220 superwash.
