As long as I'm showing off Mom's quilts today (and working from her computer where these pics are stored), here's the one that she made for me and Ted. I actually bought the fabric with her when I was fresh out of college and still living in Iowa City; we went to a quilt fabric store outside the Amish community of Kalona, where Mom nearly swooned at the variety on sale (this was pretty much before the Internet, so quilters were usually stuck with their local sources only, such as JoAnn Fabrics).
The Double Wedding Ring pattern was popular from the twenties through the forties. A long history of this particular pattern can be found here, but in summary, the motif of interlocking rings is quite old, stretching back at least to Roman times.
At present, we have this one packed away because Ted and I are basically still sleeping on a mattress on the floor. We'll assemble the bed one of these days, before the crick in my neck becomes permanent. Hard to believe I used to be able to sleep sitting upright on overnight trains across Europe back in my younger days.
