Winged heart motifs have been popular lately. The focal point of this design is a heart-shaped Czech glass button, which is nestled on top of two paper flowers. This configuration sort of reminds me of winged hearts -- I like it!
Underneath, I have a hand-painted fabric heart. I used Lumiere metallic paint to paint two different cut-out muslin fabric hearts. I then stitched them together with wrong-sides facing, turned them right-side-out, and stitched around the edges with red DMC embroidery floss. Note that Lumiere is a great fabric paint, but it does stiffen the fabric quite a bit. That's ideal for this particular project, because I wanted a good stiff background to support the Czech-glass button, which is heavy.
Obviously, this design is not washable if you duplicate it exactly. If you like this idea but want a washable version, skip the paper flowers and the delicate glass button; instead, use washable embellishments on top. You could use felt flowers or a single crocheted flower -- I think two might be overkill, considering that crocheted flowers are much thicker and more dimensional than their paper counterparts are. There are also plenty of washable buttons available which can be substituted for the Czech glass button.
