Although this block would seem to be only an enhanced version of Week 2's North Star, it was quite a bit peskier. It is a pretty star and I do like the way these particular fabrics worked together.
You have those places where the points of the center square on point meet the large background flying goose triangles - after all, you can only be looking at one side at a time while you're sewing. Then, there's that the intersection of the background corner squares with two sets of the paired small triangles to be careful of. Most of this went together fine for me, using my triangle rulers designed for half square and flying geese triangles, but I did baste the last two long seams before sewing and will admit to pulling out parts of one of those last seams more than once.
It turns out pressing is as important as accurate seams in making all the lines match up where I wanted them to. One pair of points that doesn't line up in the photo actually does when held flat. All I can say is, it's a good thing I'm my own quilter.
