The pattern of Anderson the seal can be found in the book Pica Pau 2 of Yan Schenkel. This book contains all kind of colorful animals with great accessories attached to it. Anderson has a hat and a scarf which is crocheted in one go in the body. This is also the most difficult part of the pattern but I am always in for a challenge. You need to know how to smoothly switch colors and crochet a jacquard pattern using a diagram. The result of jacquard pattern is more beautiful using single crochet stitch with the X look, this is all explained at the Pica Pau Instagram page, @picapauyan. It was the first time that I used it and I was so pleased with the result that I am crocheting now always with this stitch.
