RE: Anyone have Crayola double easel?
I don't have a Crayola, but a lot of easels have the plastic-y chalkboards, and it can be kind of hard to see certain chalk on them.
We have a different easel, but the whiteboard doesn't always wipe off completely. YOU can still see the outlines. But if we wipe it down with a microfiber cloth and some cleaner, it gets it really clean. I just do that periodically when it gets really bad. Day to day, DS doesn't mind. He actually likes tracing over the letters that get left behind when I write on it.
My point is that those concerns probably extend beyond that easel. A lot of easels are going to have similar issues. How much it bothers you is another story ;)
