Mkotch, those are so lovely! The paper-piecing does use up lots of fabric.
I am definitely getting better at the Y-seams; this time only one of the units was significantly shorter than it should have been. While putting together my first version of Mill Girls, I discovered I had almost no seam allowance beyond some of the points, so I started over from scratch; I must have carelessly trimmed the quarter blocks. Fortunately, that isn't part of my original fabric bundle that I'm running short of.
Here are my blocks for this month. Now to get back to the July applique block, which is coming along slowly.
