The top one is week 48 Knotted cable Chain stitch which looks very nice in this variegated thread as each one has come out a different colour.
Not a hard stitch to do either.
The background fabric is a lovely lemon shade but here it just looks a dirty colour.
Week 49 is pistil stitch and I quite enjoy doing this stitch maybe it's the French knot bit on the end.
I started out thinking I would do some flowers and after a few of them they began to look like snowflakes so then I found some fancy thread I think it's called Glisten Gloss but I'm not sure ,but they definitely looked like snowflakes-if you click on the picture to enlarge it you can see the sparkle.
The fabric is a fine even weave linen and the other white thread is perle 5.
