I span 250 grams dog yarn, 2 ply, most of it is “samoyede” dog.
Then I dyed the yarn using parmelia saxatilis lichen, just a few pieces, to obtain a straw color (initial samoyede was white).

I asked the designer of “gilet sans manche tulipe” for some help about sizes and total weight of the vest, but she totally ignored me, so I decided to adapt her pattern to my own needs.
