Well, it’s really one swatch.
Here it is before washing:
It’s 3.75″ from top to bottom. I washed it using a hot wash/cold rinse and then dried it on the hottest setting in my dryer. Here it is (sorry for the blurry pic):
It is now 3.25″ from top to bottom, but the same width. And it is magically transformed from string to nice soft squishy cotton.
Lucy has given up on supervising me.
