Striped Quilt tutorial part 2

 I am not using a pattern for this quilt, which can make fabric requirements a bit tricky.  What I have done is devise 2 blocks of the same size (18" unfinished").  Block 1 starts with a 6.5" centre square, followed by a contrasting 2" row, then a 2.5 row and finishing with a 3" row, in the Square Within a Square style.  Above, I've cut strips in these widths to start the blocks in the yellow colourway.

 Here's the first 2 rows of Block 1...

 Three rows....

 ..and the completed block.  I made a second block starting with plain in the centre, ending with stripes around the outside.

Here's Block 2.  The cutting sizes are 5.5" centre, 3.5" strip for row 2, 2' strip for row 3 and 2.5" strip for row 4. 

Here's the 2 different versions of Block 2. 

All the blocks are then cut into 4.  I fold the block in half one way and finger press the fold, then cut along this with a rotary cutter.  Repeat for each half to get 4 identical quarters. 

Once all the 4 blocks for each colourway are completed, the blocks will be re-assembled into 17.5" blocks with each quarter being of  a different colour.   As the strips of the 2 block types have different widths, there will be no need to match stripes.
