Half the squares, twice the fun

My quilt guild's Block of the Month this year is called "Half Square Triangle Sampler" by Jeni Baker.  All the blocks are made up of only Half Square Triangles.

The pattern directions are for 12" blocks for a nice lap size, but I have decided to make my blocks in a 6" size instead.  I want to use a couple of charm packs that I purchased a while back at an overstock sale:

When I opened up the wrapping, I realized that it contained multiples of only 7 different fabrics.

I checked the stash to see if I had anything to add, and I came up with these additional fabrics:

(Hey Linda N!  Notice the blue/green ginko leaf fabric.  It lives!)

Each of the fabrics will be paired with white to make up the HST's.  I cut the white fabric into 5 inch squares and marked them with an "X" from corner to corner:

Then sewed 1/4 inch on each side of the line:

and cut apart into squares.

Each square generates 2 HST's:

So, instead of drawing a diagonal line on the back of 4 small white squares, I only had to draw 2 lines on the back of one larger square.  Works for me!

Here are my first two blocks of the Sampler:

My quilter friend, Rosemary, is also making the guild's BOM.  You can see her blocks here.
