Success! Retro Chic quilt top finished, the backing pieced, batting cut to size, and quilt sandwich assembled. Much time was spent on my knees bent over the quilt sandwich for pinning. I think I need a visit to the chiropractor.
I quilted said sandwich during pockets of time I made for myself by ignoring household duties. Since I only know how to stitch in the ditch, stitch in the ditch it was. I learned the hard way that one should not attempt to do this after having a glass or two of wine. A very nice glass of Malbec caused me to wander in and out of the ditch a few times, as you can see below.
Here's the worst offender. I think this was after the second glass.
I've moved on to piecing the scrappy binding. I wanted to use only the big print fabrics left over from the blocks, but after sewing up everything I have alas! not enough binding. So, I'll be un-sewing parts of the binding to add another fabric to the mix. Un-sewing: it's what I do best. Ah well, it gives me an opportunity to fix the part of the binding where I accidentally reversed the fabric order. Silver lining :)
