One of my favorite card designs for a 5 x 7 card is the 'Bullseye' pattern from Wishes. I created this card with Emporium papers and the stamp set - You Are Beautiful.  I added a little bling with Twilight twinkle brads and some glitter...
here's my 'Glitter 101' tip:
Don't use glitter near a fan!!  I have to stay I am still sparkly!
I guess I should invest in an air conditioner for my Creation Station, but I'd much rather spend money on CTMH product!
