I started by going through me stamp sets labeled "floral" to find a bouquet that would work well with hearts covering the flowers themselves. This set is quite old, but had enough space between the flowers to accommodate the heart overlays. It took a bit of searching to find stamp/die sets that had the right size hearts to work on the bouquet, but I am really happy with the way it turned out. I used glacier, raspberry, wisteria, peach, flamingo, lilac, and canary inks for the hearts. I also colored the flowers that were below the hearts in a similar color since some of the flowers peak out behind the hearts. All of the hearts have some foam behind them to give dimension to the card front. The "just for you" sentiment (M1309) is from one of the new mini greetings sets.
There are several papercrafting challenge blogs that had a theme that worked with this card. Here are the links to each of these blogs so you can check out the other creations with the friendship/love/heart theme.
