I got out my brand new Guide Lines stamps from Papertrey Ink and I have to say that I am in love with this set. You can make your own patterned paper in a flash and even if your lines aren't perfect--you can hardly tell.
I started out with Spring Moss ink and stamped my lines. Then I filled in with different design elements from the set in Plum Pudding, Lavender Moon, and Spring Moss. My lines were far from perfect, but once you add the other stamps it is not noticeable (unless you're studying the paper and who does that?). I hope to use this on a card soon.
If anyone else has this set from PTI, I'm sure you see as many different possibilities as I do. Can't wait to try out all of the colors.
