The flower is very easy to make once you understand how to fold the petels. Took me some time before I got it but after that it was peanuts making them.
Yarn: Schachenmayr Catania (but the pattern works with any kind of yarn)
Crochet hook nr. 3 (Europe)
Chain 6 and close with a slip stitch.
Chain 3, crochet 3 treble crochet in the ring, chain 3.
1 tr in first tr, 1 tr in the next 2 tr, chain 3
Fold the petal backwards and crochet *1 tr in the ring
3 more tr in the ring, chain 3
1 tr in first tr, 1 tr in the next 2 tr, chain 3*
fold backwards again and repeat everything between the *
Repeat untill you have 7 petals, close with slip stitch.
Stick a pretty brad through the hole and glue a magnet on the back. Done!
