I've found this pdf to download at Crochet Pattern Central website.
I'm in love with vintage style hats, and this pdf is really amazing.
It has thirty-six hat patterns to make, and the first I've tried is the no. 27.
I've made some modifications to have it more like a beret than a beanie, here there are if you want it like mine:
Follow the pattern till Rnd 6.
Rnd 7: Ch 14, *dc in next dc, ch 11*. Repeat from * around, sl st to third ch of ch 14.
Rnd 8: Ch 16, *dc in next dc, ch 13*. Repeat from * around, sl st to third ch of ch 16.
Rnd 9: Repeat Rnd 8.
Rnd 10: Repeat Rnd 7.
Rnd 11: Repeat Rnd 6.
Rnd 12: Repeat Rnd 5.
Rnd 13: Ch 3, 5 dc in ch space, *dc in next dc, 5 dc in ch space*. Repeat from * around, sl st to join.
Rnd 14: sc in same st as joining,*skip 2 dc, 5dc in next dc, skip 2 dc, sc in next dc*. Repeat from * around, ending with a sl st in first sc of round.
I've added a flower on a side with a mother of pearl button in the centre..it gives a more stylish touch!
Here's a picture of the back:
That's it..hope you'll enjoy this pdf too!
