Here's a 'seam treatment' idea, and flowers, and single 'filler' stitches, and- great discovery - the long-stalked variety!
I like the way you can pack this stitch together - the cream-green-brown-gold bit.
Bits of the next stitch - palestrina - creeping in at the bottom. That's the thing with my continuous strip, I don't really want gaps. And the long stalks a bit closer.
I like doing small amounts of stitching on small bits of felt, a sort of rival / companion to the main strip.
Why is an oyster stitch so called? Does it look like an oyster? Maybe a bit like part at least of the live thing inside the shell I got interested in the long stalk possibility and began finding things to do with the stalk - couch down with various stitches, wrap loosely, wrap with buttonhole (buttonhole bar) . . .
