(Lavender blue for WHY does the camera pick up only the blues and not the purples...)
I was picking the circles up off the floor and placed them on this book, which gave me an idea:
I might be able to find a piece of linen to stitch on, and then place the circles on top.
I'm treating myself slowly to back posts of jude from Spirit Hill: she uses so many different fabrics/weights, and to great success.
And she thinks outside of the box for stitching.
