Thanks everyone for all the tips and tricks. I'm waiting for the fabric to arrive as I type. Once it does I will definitely contact the LA'er to see how she wants it treated. Since all of the other fabrics are pre-washed I will minimally do that regardless. But as to specifics of pressing, I'll rely on her preferences.
I want to make sure I have all of this in hand before I commit to giving her either 2 or 4 quilts on Fri.
