I’ve slipped down the tree trunk and begun some vegetation. The fern is Double Cast-on using Brazilian Lola thread, No 167. The flower is Kiko’s flower stitch, made with perle 5 thread and the centre is done with a fine twist cotton- 3 x 2 wrap French Knots.
The Double Cast-on can be found in a 2+ minute video, using the highlighted link above. I used 3 long sewing needles to get a wider stem.
If necessary, for anyone interested I can post photos of the way the needles are used.
