For the curtain over the sink I used the top of the shower curtain so the curtain rod could go through the grommets to hang it. I just trimmed it to the right length, doubled it over and sewed along the seam under the grommets to hold in place.
For the curtain in the shower room I used the bottom of the shower curtain and doubled it over and sewed across the bottom. I then sewed 2" & 4" from the top to make the casing for the curtain rod.
Here's a close up of the shower curtain. I got them at Target on Clearance with gift cards from the wedding. The curtain rod and hooks I found at Wal-Mart and I really do think they were cuter than anything at Target or Bed, Bath and Beyond. I'm so much happier now when I go into this room. I love how everything matches.
