I think it's quite pretty.
I used another 5 stitches to finish this; 1- a daisy stitch. 2 - a french knot. 3 - long and short stitches.
4 - a satin stitch. 5 - a seed stitch.
The daisy stitch and the french knot are offcially my favourites. The silk stitch looks really nice, but I don't like that it uses up so much thread. Personally, I think the seed stitch it silly, though it is useful.
To learn how to do a french knot, I watched this tutorial: http://www.youtube.com/watch?v=bezNWJgBe0o
The same lady did all the tutorials that I learned from. Though I watched her tutorial for the satin stitch, I did my satin stitch differently; she outlined hers first with a split stitch, but I outlined mine with a basic backstitch. I didn't want my hearts to be quite so puffy.
I'm already working on another sampler, but I'm doing rounds instead of rows/patches. I will, of course, post photos.
