You could use any yarn weight for these bunnies as long as you choose a fitting hook, it will only influence the finished size. My example rabbits were made with DK yarn and 3mm hook, they are about 8" long and 6" tall to the tip of the ears. The pattern is 9 pages long with many photographs illustrating the process. It is written in English with US crochet terms. Stitches and techniques used: starting with magic ring, chain, slip stitch, single crochet, single crochet increase, invisible decrease, work in front loop only Multiple color changes are necessary to make the typical Dutch markings, which (coupled with realistic shaping) make this an advanced level amigurumi. Finished items made from this pattern are yours to keep or gift away or sell, I only ask you to give me credit as designer in case you decide to sell them.
