The pinwheel blocks are coming along a little bit easier than they were, mainly because I'm being incredibly careful making them.
The finished blocks need to be 6" square when sewn into the quilt, so at this point, before they are sewn together they need to be 6 1/2".
I begin by cutting two white 4" squares and two coloured 4" squares. I draw a pencil line diagonally across the white squares. 4 1/2" is slightly larger than most directions will specify, but I want to have the extra fabric in order to trim the squares precisely later on.
These squares are place on top of each other and the seams are "nested" into each other. The squares are sewed together with a scant 1/4" seam.
When this block was turned over a "boo boo" was found. The seam underneath had wrinkled a bit. So we take our stitch ripper and take out a few stitches, then sew the block back together with smooth seam allowances.
This seam is pressed halfway on each side, so that on each side the fabric is pressed toward the coloured cloth.
Take the stitch ripper and very carefully pick out the stitches in the seam allowance of the seam you just crossed over. Fold those allowances back and you get this pretty, tiny pinwheel that allows the seam to lie flat on either side of the centre crossing.
Turn the block over and have a gander:
Not really quite as precise as I had hoped so I'll have to use the 4 foot rule. Does it show from 4 feet away? If not, don't redo.
I think this particular block might undergo a bit of revision, but on the whole, the meeting of points in the middle is improving.
