She's actually showcasing the perfect way on how to use up some of that Designer Series Paper that we all have stashed away...
Since the sheets of DSP in one pack coordinate so perfectly it would be very easy to make cards like this for many occasions... Melissa even shared the measurements with us...

Mint Macaroon (Accent and Banner) 5 1/4 x 4 (accent) 1 x 4 (banner)
