Photoshop :: Removing Ink Bleed Through Paper?

I have some art I did back in high school that I recently scanned in. They are just pen doodles that I did on regular lined notebook paper. But on some of the pages I drew on both sides of the page, so when I scanned one side the ink from the other side bleeds through. I'd like to remove those portions but keeping the original lined paper look.

I tried content-aware fill, healing brush, spot healing brush, and more but nothing seems to work quite right. I seem to have the best luck with the patch tool, but for the parts selected close to ink, the replacement patch gets blue ink blur. It's like Photoshop is trying to guess what should go around those edges but all I want is just the plain selected area CS5?
