The finished rainbow is approx. 23 cm wide. The clouds are crocheted in continuous spiral rounds and the rainbow is made out of two pieces, crocheted in the row. The pieces are then sewn together. The turning chains don’t count as a stitch. Use the yarn and matching crochet hook of your choice. The result will be bigger or smaller, keeping the same proportions. In my blog entry for this pattern you find videos for the invisible decrease, how to close the last round and how to do the mattress stitch. A list of the used materials is there aswell.
