My clipboard

I'm almost done with my clipboard! And I'm very pleased. I'm not entirely done, but I'm not sure what else I'm going to do... I'm working on layers of mod podge now. Beth just told me I need to do at least 4 coats of it to protect and seal the papers in... Is that true??? I was surprised. I thought 2 was enough, but she generally knows way more than me about craft type stuff.
I'm looking forward to enjoying my lovely craft piece in the grocery store. ;)
