You said you want a 'coastal' theme. When I was living on the beach I found a great LQS that had lots of beachy fabric. That's what I used for the shower curtain I made. It was a peach color of sea shells..... loved it. Try looking for your fabric at LQSs along the coast. Good luck.
ps- I know how frustrating it can be when you're getting ready for a move..... my family calls me the moving queen. But, once you get things packed, just sit down, sip a glass of wine, and think about how wonderful it will be in your new sewing area. It works for me, every time.
