Block {THREE} of the Mystery!

i know that you are all dying to get this done, so here's block {three}
you will need to make {8} blocks that look like this.



start by sewing together one dark and light strip
like this...

then sub-cut the above pieced strip into {eight} 1 3/4" units.
following the diagram below, piece together the {eight} half-log cabin blocks.

as a side note...
i didn't like the method above ( my blocks got a little wonky) so i cut the following and pieced the blocks together with the individual cut pieces rather than long strips as shown.

From the light strips, cut...
{8} 3" units, {8} 4 1/4" units, {8} 5 1/2" units

From the dark strips, cut...
{8} 3" units, {8} 4 1/4" units, {8} 5 1/2" units and {8} 6 3/4" units

So, for example, once you have your {8} 1 3/4" units pieced and cut, cut and sew a 3" x 1 3/4" light unit to it (as shown in the above diagram). Then cut and sew a 3" dark piece to it, then a 4 1/4" dark piece to that, and so on...
it takes a bit more work, but the end result is a truer block. it should measure 6 3/4" square.

hope this make sense. holler if you have a question.
