There seems to be a bit of a 1/2 square triangle theme going on these days.
For this block, I paper pieced the sides for the second border from the outside. The angles were not 30, 45, or 60 degrees, so the cutting would have been a little tough.
Here is the block set out with the 1/2 square triangles and paper piecing completed for the outer borders. When cutting, note that the centre is not composed of squares. And that they're all different sizes to boot!
I started working on building the strips for each of the outer border along with centre block, paying attention to placement of the pieces. (Did I mention that they're not all the same size?? :)
Continuing to pieces the middle of the block and border strips. (Yes, I ended up un-picking the middle a couple of times. Did I mention that they're not all the same size?? :)
The strips for the outer borders are complete! And I've added the first border to the centre of the block.
