Disappearing Nine Patch - Part II

I have sewn all of the three patch rows into nine patch blocks - nine of them in total.  The blocks are all basically the same with a red value patch in the middle and a 'colour' at each corner.  The remaining blocks are cream.

Having spent several hours carefully sewing these patches together I am about to cut them up.  Yes!  That's right - I haven't gone mad.  I made one cut vertically down the centre of the block using the seam line to help me.  The cut has to be made two and a quarter inches from the seam.  Another cut is then made horizontally across the block again two and a quarter inches from the seam lines.

Now the nine-patch block is separated to make four asymmetrical four-patch blocks.  I repeated these cuts on the remaining eight nine-patch blocks.

The result is 36 four-patch blocks - six of each colour.

These blocks have gone together very quickly.  Since I shortened the belt on the Singer 201K it hasn't slipped once and the machine, which was fairly enjoyable to sew with, has become a joy to use.
