I started by washing and drying the fabric so that we didn't have shrinkage problems later. Then the fabric got ironed out nice and neat and forgotten about for a few weeks (you can totally skip this step). Then it got re-ironed when I 'found' it again. Instead of using a ton of pins I ironed all the folds and then added a few pins just to make sure that things didn't get all wonky. The seams on the sides and the bottom are 1/2 inch. At the top there is a 1/2 inch fold under and then the pocket to run the rod through is 2 inches.
