I always wash in hot water, and dry in hot dryer to shrink as much as it will before cutting. Due to its propensity to ravel extensively, I use a very narrow zig zig stitch instead of a straight stitch and a slightly larger seam allowance (make sure you take this into account before you cut). I have made PJs about 10 years ago for one Grand daughter that have been passed down to middle sister that youngest one is now wearing....they are softer and slightly faded, but still holding strong.
