Midsummer Baby Blanket with Tiny Hat

This pattern might look more complicated than it really is. It´s just knit stitches and slip stitches all the way. It is very effectful, and fun and easy as a Summer project. Also, it´s soft and lofty and just perfect to welcome a Summer newborn to the world. A cute hat goes with the blanket.

Hat
Cast on 48 s on DP needles US 5.
Knit stockinette in the round and change colours every 1.6".

Start decreasing when the hat is about 4.3".
Round 1:
*K6, K2tog*
Repeat from * to *
Round 2:
Knit

Repeat these two rounds, but substract 1 s in between the K2tog per round of decreasement, ie. K5, K2tog next time.
After you´ve knitted a round of decreasements with 1 s between the K2tog, change to the last colour and K2tog for an entire round.
On the next round K2tog until you´re left with 4 stitches.

Make an i-cord of these stitches by knitting 4 s, slip all s from the left side to the right side of the right needle. Bring the yarn in back, and knit 4 s from the same direction again. Repeat until you can make a small loop and assemble to the hat.
