This hat began as a doodle during my travels up to Vermont to see my folks. I was playing with my favorite old doily pattern - The Plate Doily, from 1917. As the doodle grew, it was feeling really nice in my hands; a good floppy drape, but sturdy.
It grew throughout the weekend. At a concert a friend asked what I was making. I said I don't know, probably a hat! I decided to put a brim on it when I got home, and Voila! a sun hat!

E - 3.5mm hook
less that 200 yards fingering weight cotton thread (I used Numei cotton breeze, color: shell)
yarn needle

hat measures 7 inches, 18 cm wide at top, 3 inches,7.5 cm high for the side, and the brim is 2 inches, 5 cm wide. My head is 22 inches, 56 cm around and it fits me well, a little on the snug side so it stays on in the wind, but does not leave it's mark on my forehead when I take it off!!

6 sc per inch, 6 sc per 2.5 cm

The reason I love The Plate Doily Pattern is that you really get into a rhythm once you get to know it. It progresses with a very simple logic that is easy to follow.

The pattern is worked in two parts.

Part one - increase one sc between each ch3 loop for each round
Part two - decrease one sc between loops and increase 1 ch3 loop per round

The pattern is worked in the round with no joining or turning.

Now you know the basic logic behind the pattern and you are free to play with it as you like!

Okay! My work is done.

Ha! Ha! Just kidding!

Below is a full round by round write up of my sun hat!

worked in the round with no joining or turning
mark the first stitch of each round to keep track of rounds

Top of hat

note -
You can adjust the width of the hat by adding or subtracting rounds before round 11.
Continue the pattern of increase if you add rounds.

1. 8 sc in magic ring, or work 8 sc in a loop made of ch3 joined with a slip stitch if you must!
2. 2sc in each sc around
3. (sc, sk 1 sc, ch1) repeat around
4. (2sc in next sc, skip ch1 loop, ch2) repeat around
5. (sc in next 3 sc, ch2) repeat around
6. (sc in next 4 sc, ch2) repeat around
7. (sc in next 5 sc, ch3*) repeat around *note loops are ch3
8. (sc in next 6 sc, ch3) repeat around
9. (sc in next 7 sc, ch3) repeat around
10. (sc in next 8 sc, ch3) repeat around
11. repeat round 10
12. (sc in next 7 sc, ch3, sc in next ch3 loop)* repeat around
*note sc in next ch 3 loop means place the sc around the ch3, not in any one stitch
13. (sc in next 6 sc, (ch3, sc in next ch3 loop)2x ) repeat around
14. (sc in next 5 sc, (ch3, sc in next ch3 loop)3x ) repeat around
15. (sc in next 4 sc, (ch3, sc in next ch3 loop)4x ) repeat around
16. (sc in next 3 sc, (ch3, sc in next ch3 loop)5x ) repeat around
17. (sc in next 2 sc, (ch3, sc in next ch3 loop)6x ) repeat around
18. (sc in next 1 sc, (ch3, sc in next ch3 loop)7x ) repeat around
19. (sc in next ch3 loop, ch3) repeat around
20. (sc in next ch3 loop, ch2*) repeat around *note loops are ch2
21. (sc in next ch2 loop, ch1*) repeat around *note loops are ch1

Side of hat

note -
You can adjust the height of the hat by adding or subtracting rounds in this part.

22-25. ((sc in next ch1 loop, ch1)x7), ch3 repeat around
26-30 ((sc in next ch1 loop, ch1)x5), (ch3, skip 1 ch1 loop, sc in next ch1 loop)x2) repeat around

Brim of hat

note -
If you prefer a less ruffly brim, make fewer stitches in round 32
ie (2sc in next sc, sc in next 2 or 3 sc) instead

31. sc in each sc and ch1 loop around
32. (2sc in next sc, sc in next sc) repeat around
33. sc around
34. (2sc in next sc, sc in next 5sc) repeat around
35. sc around
36. (sc in next sc, skip next 2 sc, ch3) repeat around
37. repeat round 35

I hope the directions are clear and that you have fun with this pattern!
