I have now made 2 leggy frog crochet patterns
Small leggy frog - made with super chunky yarn and a 4.500mm hook (you may need to go up a size)
Large leggy frog (which is a separate pattern ) made with chunky yarn 4.500mm hook
or you can make this leggy frog into a keyring using Double knit yarn and a 2.5mm crochet hook
