You can imagine my elation out shopping at Tar.get, when I found these clearance shower curtains, lined and in beautiful masculine/feminine patterns:
I got them for a steal at half off: $15/ea and took them home to set to work. Mind you, this is an EASY DIY--I am no seamstress. Anyone who can sew a hem can do this. You could also work it with sewing glue if you don't sew. It's definitely not rocket science!
I first cut my curtain in half--the dimensions are 72" x 72", so I knew I'd have plenty of curtain to cover my windows.
You'll now have two separate panels, each with a rough edge.
Mama's best helper
Now fold once and twice on your rough edge and pin. You'll want to have 1/4" to 1/2" stitch allowance.
Then set to sewing your seam.
Take that, PBK!
