All finished and heading off for the pile of tops still waiting to be quilted.
This is how it went. Lots of bits were not sewn at this point, because I was trying to figure out that top left corner and the right hand side simultaneously. When I laid out the bits on the right, I thought I was right down to the wire, in terms of remaining fabric. I was hoping to be have enough squares and pinwheels to fill in all my spaces, but was still trying to keep an eye on how things balanced across the whole top. Lucky for me, I found one last, biggish piece of shirt big enough to cut several chunks from and that presented me with a much quicker solution in that top left corner. It is a note to self - sometimes I only use a small amount of a fabric, because it seems to me to be having an oversized effect on the quilt as a whole. That's fine, but I should really keep better track of where I put the left-overs! I would have been pretty fed up if I had only found that fabric after I'd finished piecing.
