Pattern for Crochet Blanket

Okay, here is the pattern for the Knitathon blanket I made. This is my first attempt at writing a pattern, so if you have any questions, just send me an e-mail.

Begin with 60 chains (or any even number).
Row 1: 2dc in 4th ch from hook, *skip 1ch, 2dc in next ch, rep from * to the last st, ch2, turn.
Row 2: *2dc in center of 2dc group, rep from * to the last st, 1dc in last st, ch2, turn.
Rep row 2 to desired length.

After reaching desired length, begin the shell edge starting with the corner.
With the rs facing * skip 2sts, 5dc in next st, skip 2sts, sl st in next st, rep from * to end.
Go around the blanket and then fasten off.

Yarn: I used Caron "Wintuck". 2 skeins of Colonial Blue Ombre (4-ply Knitting Worsted Weight)
