Poppies and glitter paste

This is a cute and very simple notecard I made using glitter paste and a stencil. My goodness the glitter still goes everywhere! I love the effect that you get with this paste though as it's got a bit of depth. I would love tips on how to stop the paper from buckling though if anyone has any. I was going to use red card to mount but I decided the muted green looked better. I'm also debating whether to add a sentiment underneath the ribbon but I might wait and see what I decide to use it for first so I know what it needs to say.

Thanks for looking!
