Clipboard of my own

Here's a clipboard I made for myself. 

 The back is covered with a plastic laminate so that the flowers don't peel back.  they are thick stickers from an old, retired Stampin' Up! Simply Scrappin kit.

I need to find a way to attach a pen other than tying it to the top.  I'm thinking of a straw like tube under the clip.  Hmmm... on the hunt....
