I made a bunch of shaker-card valentines, using a new die from My Favorite Things. As soon as I saw Love Centerpieces from MFT, I knew that I had to have it, and that I wanted to dig out my stash of sequins and make some fun cards. 
Usually, when I make shaker cards, I use foam tape for the center layer. This time, I tried something new by running the die through with some fun foam, and then used scissors to expand the spaces a bit for more bling room. This let me keep each letter separated, without having to build structure with foam tape. I just used Scrappy Glue to adhere the layers together. 
I wandered through my local paper crafting store to find patterned paper that would coordinate with the different solid colors I chose. 
I have quite an accumulation of sequins from Doodle Bug, Papertrey Ink, Lawn Fawn, but I have to give a shout out to the Pretty Pink Posh Sparkling Clear sequins. They add such a nice silvery shimmer, without being too distracting, especially if you have other colors in your mix! 
Here’s what the back of the cards look like: 
FYI: I made custom square envelopes for these cards (5″ a side), which meant extra USPS First Class postage ($0.70 to $0.91). I’ve pinned a reference sheet on First Class Postage here, but I have had good luck using two “Forever” stamps for my shaker cards and/or square envelopes.
