I'm going to make 4 patch components (and twirl the seams clockwise), then assemble the final blocks as 9 patches.
The plan... (My! that sounds efficient and organized, let me say that again)... the plan is to end up with a 60" x 72" flimsy (12.5" blocks laid out 5 x 6). The calculator tells me that 30 blocks will use 1,080 HSTs from the box containing about 1200. This seems like the most efficient way to proceed. I can either chain piece in a marathon session, or I can proceed with it as a leader n' ender, or do it in a combination of both approaches.
Each block has 4 of these corners = 120 light left leaning lazy diamonds
and 120 dark left leaning lazy diamonds (30 blocks x 4 corners)
And 1 of this 4 patch for each of the block centres = 60 dark flying geese
And each block requires 4 of these units = 120 dark flying geese and 120 light flying geese
I've written down the components I need on a post-it note that will sit on my sewing table. I foresee a lot of counting in my immediate future. I shall be very pleased to finally get these HSTs used up in a quilt top and off my unfinished list. They have been on the back burner for almost ten years.
And to think, ten years ago I actually thought this was a good way to use up fabrics I didn't like in a quick scrappy project! If you're laughing, you've got one of your own tales of woe to tell.
Now I think I'll enjoy a little mindless scrappy sewing in what's left of my Sunday. I've got some foundation squares starched for string blocks, the 1.5" strip box open on the sewing table, a pile of teeny crumb strips to use as a leader n' ender, and a fresh pot of coffee brewed.
