In the last few days I added a lot of stitches to my second design for Sharon's Sumptuous Surface class. Most of them were new to me. The first one is a pulled thread stitch, single cross eyelet. Another pulled thread stitch, the hexagonal eyelet.
The last pulled thread stitch is the triangle stitch. It gives a nice pleated look.
The cushion stitch is a needlepoint stitch. This one was very easy.
Milanese stitch is also a needlepoint stitch.
I found the pulled thread stitches in the book 'Pulled thread embroidery' by Moyra McNeill.
