House Unity Blanket

Hello, folks!  In preparation for Part I of the Deathly Hallows movie(s), I decided to make a house unity blanket!  If you don't know, that just means that instead of choosing one Hogwarts school house, you use all four main colors.  This is a fairly quick knit on large needles, and can easily be completed in a weekend.  I used 15mm needles and two strands of worsted weight yarn held together.  (As per usual, I used Red Heart Super Saver yarn)  For colors, I used "Black" as my main color, "Bright Yellow" for Hufflepuff, "Paddy Green" for Slytherin, "Ranch Red" for Gryffindor, and "Blue" for Ravenclaw.  This is a very simple pattern.  Finished piece measures approximately 4'x4'

The basic blanket is worked as follows:
Use wither a super bulky yarn, or two strands of worsted weight held together.
With black, cast on 3 sts.
Row 1: K1, YO, Knit to end of row.
Repeat Row 1 84 times. (87 sts)  (This is 4 rows past the second red stripe)
Row 2: K2tog, YO, Knit to last 2 sts, K2tog
Repeat Row 3 until 3 sts remain, bind off

At the same time, work the following color pattern:
8 rows black
2 rows yellow
8 rows black
2 rows green
8 rows black
2 rows blue
8 rows black
2 rows red

If you'd rather have a pattern matching the Prisoner of Azkaban style scarves, work the following color pattern:
10 rows MC
2 rows CC
2 rows MC
2 rows CC

For Gryffindor, use Ranch Red and Gold,
For Slytherin, use Paddy Green and Light Gray,
For Ravenclaw, use Blue and Light Gray or Warm Brown,
For Hufflepuff, use Bright Yellow and Black.

Make 4 tassels, one in each color (or all MC for single-house blankets) and attach to the corners.

I make tassels by wrapping the double-stranded yarn around a DVD case about 25 times, tying across one end, and cutting the other end, then tying around the whole bundle about 1.5" from the tied end.
