If you are new to crochet and in search of practice pieces or just looking to crochet something that is easy and fast, Easy Round Motif is perfect for you.
For the big one, 8,5 cm (3,3 inches) in diameter, I used cotton thread size 3 and a 3,5 mm crochet hook. I crocheted the small one with variegated thread DMC Babylo 10 and a 2 mm crochet hook. Its final size is 6 cm (2,4 inches) in diameter.
Besides your chosen thread and hook, you will also need a needle to weave in loose ends and a pair of scissors.
