A Twisted Path Quilt Tutorial

I received several requests for a pattern tutorial. This is the first time I've ever done this, so I welcome some friendly tips for better pattern tutorials in the future.  Enjoy!

Quilt Size:
40" x 44"

Materials:
14 fat quarters
1 yard neutral solid

Cutting Material:
Cut 4 - 5 in. squares from each fat quarter.
Cut 56 - 5 in. squares from the neutral solid.

Half-Square Triangles:
Here is a great tutorial on making HST from Connecting Threads.
Your 112 HSTs should measure 4 1/2 inches once they have been trimmed up.  You'll have 2 HSTs left over.

Laying Out Pattern:
Start out by laying out the pinwheel in the lower right corner.

Add the next layer of HST around the pinwheel.  Notice the twisting effect starts here.

Add the next layer, again.  Follow the pattern.

This is now the completed lower right corner of the quilt.  You will be adding 4 more columns on the left side and 5 more rows on top.

Here is the original quilt displayed on the design wall.

Sew the HSTs in each row together and then sew the rows together.  Make sure to keep your HSTs and your rows in the right order, or the pattern will be distorted.

Lap Quilt Size Alternatives:

Lap Quilt (60" x 66"):
Keeping the same number of HSTs, cut 7-inch squares from your fat quarters and your neutral solid.  You'll need 2 yards of the neutral solid.

or

Lap Quilt (56" x 60"):
Add an additional 4 columns to the left side and 4 rows to the top.

Cut 8 - 5 in. squares from each fat quarter.
Cut 112 - 5 in. squares from the neutral solid.  You'll need 2 yards of this fabric.
