I decided to revisit the project again, this time using a heart punch.
I punched all the hearts from a variety of different patterns and laid them out on a piece of cardstock to figure out where I wanted each one placed. Once I had them all organized I adhered each heart using a foam square.
This time I also added a couple little accents: tiny pearls and some acrylic hearts (from an older Fancy Pants acrylic sheet) attached with mini-fasteners from Tim Holtz. Pattern papers came from my scraps. I wanted papers that included primarily yellow, orange, a bit of pink and a bit of gray - thinking a cross between Valentine's and spring.
EDITED : About the frame and mat, I have had this one for years (7+). Most likely I purchased it at either Target or Fred Meyer. The size of the opening is 8x10. A nice thing to look for when selecting a frame for this project is the double mat with the second mat lifted up off the first - it makes room for the dimension of the punches (that comes from the foam squares). I used a piece of swiss dot cardstock for the background.
Simple. Fun. Easy. I love punches.
