I'm on my second Badminton Skort. The first one came out beautifully (thanks for the great directions!), but my daughter didn't like it. Fortunately, she has a cousin who did. My daughter didn't like the scallops (so I've left them off), and she didn't like how high the waistband was. I want to make it about 3/4" shorter. My question is -- does it matter if I trim the pattern from the top or the bottom? I'm assuming I should trim the front waistband pieces and the back the same amount. How do I figure out the max amount I can trim without messing up the elastic casing? Thanks.
