This pattern is for an amigurumi frog. You will need small bits of black and white yarn, plus a main body color and accent color. This pattern is written in continuous rounds. I used a 4.0 hook with worsted yarn, but you may use different weight yarn and adjust your hook size accordingly. Frog will turn out bigger or smaller based on what size yarn/hook you use. Materials needed are yarn, hook, yarn needle and poly fil. stitch markers and stick pins may also be useful to you.
