The stranded DMC was no problem, so for the second one I tried perle 5 and 12. I made French knots and pistil stitches. There was no damage to the threads.
For this buttonhole wheel I used stranded DMC again. The edge is a trellis stitch. I also added a lot of French knots.
For the fourth ATC I found a piece of lace that was just the right size. I made 2 rows of Chevron stitches and added some beads.
