I left off leaning toward a rectangle with stars going diagonally (here) on my stay-at-home-round-robin. I pondered it a day or so and decided, No, I’d keep the quilt square, and I’d figure a use for it whatever size it ended up, or add borders or something. But my first thought was that there was way too much white space. (I know lots of negative space is a feature of modern quilt design, but it wasn’t working in this design in my head. Proportions were off, I think. By then I had the second prompt from Chris at Chrisknitssews, (The link is a generic link to Chris’ site; I will edit if I find how to get to a previous post.) the hourglass block. Maybe I could combine them.
By the time I finished making the 8 additional star blocks and the hourglass blocks, Anja at Anja Quilts had published the fourth prompt, flying geese, so I made those as well then started laying out the pieces.
For the first try. I considered keeping the diagonal star arrangement. but combining a star with a row of patterned blocks instead of a plain strip. It seemed it would work with hourglass and flying geese, and I could always repeat spool or hourglass if the next prompt didn’t work. So I laid it out.

I’ll admit to being disappointed; it had looked a lot better in my head than it did on the floor. Here it just looked cluttered and busy. I did like the positioning of the flying geese and I could tinker with using fewer hourglass blocks. Or I could try something else.
So I tried a row of three stars, now that I had 12 to work with.

So far so good. It didn’t seem to lose the spiral motion. So I added the hourglass and flying geese rows.

As of now, I think I like it. I may stitch it and stop dithering, or I may just wait to see what prompt #5 brings.
