A deep breath....and start - The Double Wedding Ring Quilt

I took a deep breath and took the fabric out of the box, with the plan and the templates.

 I had drawn this plan up per the instructions in the first flush of excitement a month or so ago. The finished quilt will be 4 rings x 5 rings,  generous lap size.  I added the reference scraps of fabric to keep track of the position numbers.

 I followed the instructions really carefully, took a deep breath and cut (and cut and cut - there is a lot of that in this quilt). And then I sewed, really carefully and much slower than normal. I came up with this.   

 A little more time and I had all these.

 Once I added the corner squares I had this.

Only 19 more to go.

Any suggestions on the background colour?
