White Kona sashing & borders lighten up the front, and help separate the Midnight Blue minky on the back. My initial choice for the back minky was a light grey because I was worried it would be 'too blue' - but the darker back worked nicely to give the quilt more visual weight.
Here's my win/win solution - I use a light thread in the bobbin. (in this case it was the middle spool of grey blue)
Aurifil 50wt. is perfect since it sinks and almost disappears into the 3mm pile of the minky. This totally works for me; no stress about thread show on the front and the back looks great since you can still see the stitching lines ... I can't wait to use more dark minkys!
