How to: Northern Lights Quilt Block - 30 Days of Sewing Quilt Blocks

Hey guys! It's day 25 of 30 Days of Sewing Quilt Blocks! Today I'm excited to introduce you to:
Northern Lights
(This block will finish at 12"x12" square.)
White fabric - 6 - 3 1/2"x3 1/2" squares
2 - 3 7/8"x3 7/8" squares
Gray fabric - 1 - 6 1/2"x6 1/2" square
2 - 3 7/8"x3 7/8" squares
(draw a diagonal line from corner to corner on these)
2 - 3 1/2"x3 1/2" squares

Place on white and one gray 3 7/8" square right sides together.
Stitch 1/4" on both sides of the draw line.
Cut on the draw line.
Press toward the dark.
Repeat, make a total of four half square triangle units.
Sew one half square triangle unit and one 3 1/2" white square together.
Refer to the illustration above for placement.
Make two of these units, exactly the same.
Sew one gray square, one white square, one half square triangle and one white 3 1/2" square together.
Make two of these units exactly the same.
Sew one half square triangle and white square unit to both sides of the 6 1/2" gray square.
Sew the three rows together.

Yay! Another fun quilt block is complete.

Now, let's see what it looks like when it's put together in a quilt top.
To make a 96"x96" quilt top you'll need to sew 64, 12" blocks, sew them together in eight rows of eight blocks.
You'll need the following fabrics.
White - 5 1/2 yards
Gray - 5 1/2 yards

For this fun version I simply rotated every other block, it's cool, it almost looks like it's on point. 
And for this fun version I simply made the corner 3 1/2" squares prints instead of gray, and it turned out so cool, the little pop of color is so much fun!

Hope you all enjoy! I'll be back tomorrow with another quilt block, click here to see all of the blocks so far.
