This charming heart pattern is from StitchPlay, the name for the designing duo of Carole Lake & Michael Bowen. They have many patterns and projects available, often through the Shining Needle Society.
On their website they have made this pattern available. There are so many things to like about it, it can really show off a lovely overdyed thread, it can be customized so many ways, and it will give you lots of practice in two stitches people often find difficult, Rhodes Heart and Waffle.
Check it out.
