Hello friends! I hope summer is treating you nice.
We are still melting over here. I can barely make myself move, let alone touch my hook. Luckily, I managed to take photos of my newest bangles I made to go with a blouse I am designing, and I thought this could be a lovely project for you as well, so today I am sharing the pattern for the bangles, but not the flowers (sadly). 
Important: The pattern is for personal use only. All property rights belong to Maya Kuzman of The Little Treasures. 

1) DK yarn and a 3mm hook (tip: for my jewelry I always use a smaller hook size than recommended for the yarn to make the crochet work more denser, tighter and neater) 
2) Flowers (crochet/fabric/felt) and beads (Links for crochet flowers below)
3) Sewing needle and thread in color of the bangle and tapestry needle for weaving ends.  
Crochet terms in American terminology: chain (ch), slip stitch (sl st), single crochet (sc), double crochet (dc).

Measurements: wrist circumference fit (16 – 17 cm)
Foundation and round 1: ch42 and join with 1st st by a sl st to close the ring. Before joining make sure that your chain is not twisted and that you joined the right sides together.
Round 2: Starting from 2nd st, sl st1 in all stitches. Sl st in the 1st to end round. (42)
Round 3: Ch1 (counts as the 1st sc) and starting from 2nd st, sc1 in all stitches. Sl st in the 1st to end round. (42)
Round 4: Ch3 (counts as the 1st dc) and starting from 2nd st, dc1 in all stitches. Sl st in the 1st to end round. (42)
Rounds 5-6:  repeat round 4
Round 7: repeat round 3
Round 8: Sl st in all stitches around. Sl st in 1st st to end round. Cut yarn and work the tail. The bangle is done. 
Now you can leave it as such, or you can spray it with fabric starch or stiffener so as to retain its shape.
There are various ways you can decorate the bangle: use beads, textile flowers, metal findings, or combine several to make this a mixed media project. 
Here are some flower and leaves patterns you can use to decorate the bangle.
Have fun and happy crochet time!
