I have tested a crochet pattern for a kimono. The designer is Maria Valles.
The kimono is composed by 2 hexagones. The construction is quite clever : the folding makes the sleeve and the two pieces are assembled to form the back.
The wool I used is the one recommended by the pattern. It is unspun wool from Island. This wool is very light but super warm. I could not find a store in the uk that sold it. The pattern requires 4 skeins : it is not much and the wool is not very expensive but I paid a bit in delivery charges.
