This shell is rather small - perfect for an ornament for a small tree, maybe at one's beach house (or in my case wishful imagining of being back in Tallahassee).
Anyway, I'm planning to stitch some of these and show progress on the other blog after I determine which threads to use. At the moment, I'm looking at one of my favorite combinations: RG Petite Very Velvet, Kreinik metallic braid (#12 for the 18 mesh canvas) and Renaissance Shimmer to make "pearls" and "coral."
Originally, I painted these little ones for a friend here in Austin, who wanted to do a small "nautical theme" tree, so this is only 3 1/4" high as is - but could easily be enlarged by either enlarging the tracing or by using the counted canvas version on larger than 18 mesh canvas.
This, again, is a tracing of an actual scallop shell from one of my books on the subject. It's easy to imagine and place "jewels" on them and change to colors to suit! Of course, many times, the actual colors are gorgeous.
The drawing on canvas is symmetric and counted, as this is a must for a small piece, especially. Also, this could be done in counted cross stitch by simply substituting the dots on canvas with an X on graph paper or fabric. Quite simple. Play with this one and see what color combinations you might devise!
