I saw a selvage quilt like this on the Selvage Blog (see side bar here and scroll down a few days). It had a red center star but when I got the selvage triangles sewn I saw a scrap of blue on the table, so I used it. And liked it and pulled out a few other blues and light purples. The design will be a spider web of selvages when several blocks are put together.
The block Karen showed on her blog was in process so I could see how it was put together. I made my own template out of cardboard after making a careful drawing of the block on some cheap paper. To my delight the template was right (added 1/4 inch for seams). Putting the block together was a bit of a puzzle, it's done in halves which are triangles, instead of the usual block within a block method. A tad harder than usual because of the biases but not difficult.
I love working with selvages. For these I used drier sheets as foundations, a favorite foundation not only for the sake of frugality but the residual bit of perfume. I'm not sure how large the final quilt will be, probably not bed size unless I just can't stop sewing selvages. I find it very fun to work with them and I like the idea of stars in these various shades of blue and purple.
The mid-70s are a surprise! Part of me remains in the 50s -- age, I mean, not decade of 20th century. It's a joy ride, new experiences land in my lap and I've become a better quilter, poet, writer than I expected. It's a rich life for a person never rich financially. Hey, this is what the mid-70s are like!
