Linked double chain stitch

This was my next TAST stitch. First I tried it with different threats (from top to bottom): DMC broder special, 3 threads of stranded DMC, perle 5 and organza ribbon. On the left I made a variation with perle 5.A few days later I made an ATC with this stitch on red felt and purple perle 5. First I embroidered a felt orange circle down with buttonhole stitches. I used those as a starting point for my linked double chain stitches. As a finishing touch I added some yellow beads.
