Here it is at last, my first self designed pattern!
Katia 100% fine merino wool or
1 5og gram ball of sport weight yarn (I recommend using a stretchy and soft merino yarn)
1 32 '' long 4.5mm (US 7) circular needle
Set of 5 4.5mm (US 7) DPNs
*When joining wool use the split splicing method. This will help you to avoid lumpy bits in the stitch pattern and save you time because there will be no ends to weave in.
*M1L: Insert left needle into horizontal bar between the two stitches from front to back. Using the right needle knit through the back of that stitch. Here is good tutorial on how to do this increase: Kategilbert.com
Scallop lace pattern Multiple 18+2
1st row: knit all sts
2nd row: knit all sts
3rd row: k1, *[k2tog] x3, [yf, k1] x6, [k2tog] x3; rep from * to last st, k1.
4th row: purl all stitches
Rep these 4 rows
Co 108 sts (36 sts on each of the 3 needles), place marker to show the start of the round. Work in 2x2 rib for 8 rows (1inch).
Next row (9): Working in stockinette st with the circular needle, [knit 6 sts, M1L] x8, then [knit 5, m1L] to the end of the row. M1L between the last stitch you just knitted and the first stitch. (128 sts)
Start stich pattern and work 7 repeats. Add more is you want a slouchier hat.
Just a warning, my hat didn't seem that floppy at this point but it was later after blocking it. Do more repeats ONLY if you want a big, tam shaped hat.
Decreasing: You can change to 4 dpns when knitting gets difficult with 5.
Row 1: knit all sts
Row 2: knit all sts
Row 3: Using all 5 dpns for this row; k2tog around. (There are now 64 sts in total, 16 sts per needle)

Cut yarn leaving a 6" long tail. Thread onto a tapestry needle and thread through the 8sts let on the needles. Weave in ends well. Block lightly and flatten out on and bowl covered with a towel.
