Welcome !
Lets make this gorgeous Lotus Pond Blanket. Lotus round motives are joined on the go.

Depending on size you will need about 700yadrs (640 meters) or more of medium to worsted weight yarn (#4), and the crochet hook H-8 or 5 mm

You can also use any yarn or thread, just make sure the crochet hook size is right for your yarn :)

Happy Crocheting! :)
