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.
