The second one is part of my border sampler. Two rows of straight single upright feather stitches in perle 5. The slipped detached chain stitches are stitched in perle 8.
A feather stitch with 2 threads of stranded DMC and French knots on this Crazy Monday block.
I made this feather stitch in perle 5 on my first block for Sharon’s Encrusted class. It's decorated with cast on stitches in perle 12.
