Thanks to all of you for your advice to make my sampler just the way I want it. In the end, I decided that both of those empty spots needed something, but just to be sure (and because I'm running low on thread), I scanned the sampler and then edited it in Paint.
So the results are below. Even though all of the letters are A's right now, I'm going to stitch "PA" (for Pennsylvania) under the CE in Peace. And I'm going to stitch my initials over the heart. Over one. Argh. It's on 28 ct. linen, but it'll still make me crazy.
So now are you completely impressed with my command of photo editing software? I should have remembered that I could do this, because I've done it before. Several years ago we were trying to take a family photo and a certain son wouldn't cooperate. We took one picture that he looked nice in, but the rest of us looked stupid. So then he refused to smile nicely in the pictures we took later.
So then I laughed myself silly, and knew that I couldn't stop there.
Yes. Clearly I'm an idiot. I'd say that I need a hobby, but....well, you know. I already have one.
