An update here's what I did: cut the fabric into 2 yard pieces, put them in the dryer with a damp cloth for 15 mins, hung them on the line and sprayed them with downey wrinkle releaser (actually a homemade version: 1 c. water to 3 T. fabric softener) and tugged on the fabric to get the big wrinkles out. Then I ironed the pieces, not using starch but using a bunch of steam. And I ended up replacing my old dinky iron with a new one that puts out a lot of steam. A lot of steps just for wrinkle-less fabric, but it worked! Thanks again!
