I never saw orange and yellow snow before !
A few words about the threads I used:
Coton perlé DMC 90 (variegated) for the seam.
For the "ferns" I used randomly DMC 90, Anchor 1305, OT 021 and Caron's Watercolours n° 176.
The stars are done with the same perlé as the seam.
For the small star I also used some rayon thread (pale yellow).The more flashy colors (bright yellow and orange) are Chinese silk I received from Mireille. They are fantastic to use!
