I love the Rhodes stitch and this is a nice variation made into a heart.
I did the first sample using Neon Rays for the heart.
This one I just used DMC floss. Both are nice. The pattern is from EGA and called For the Love of Stitching by Mary Bush. It is a Petite Project put out by the guild for members/chapters to use. My local guild, Mississippi River Valley Chapter
stitched it last month and is planning on finishing the project in May.
