The book covers aren't a bad idea. :)

I love that idea of using the covers!

Great idea!

Clever idea!

I like the idea, too!

Make that six of us! :)

That, actually, is a really good idea, kind of jealous I didn't think to do that. Will look super cool as the card fills up.

That's really a good idea!

Simple yet perfect. Kudos for coming up with such an elegant solution.

Thanks everyone! And I thought I was just being lazy about it, cause I couldn't decide what cool Halloween markers to use (one of my first ideas had been some Halloween-themed Pusheen the cat markers). But now that I think about it, it WILL look super cool if I can do a complete black out. More motivation!

I agree with everyone else. The covers look great and it will look cooler as you add more.

Great idea! & easier to keep track of I'm sure : )
