Thank you all for your comments and suggestions!
Just as added info, I did audition some other neutrals (solids) as sashing but don't have any on hand that work. They are either too cool, are not the same tone as the background of the print, or are just too different. I might be able to find a solid that closely matches the background of the print or tea dye the WOW, as Prism suggests, though that's not something I've ever done.
Feline, your point about the orange not showing up except in the closeup is a good one. I had thought I might just do a flange of the orange. Although the only flange I've attempted was a disaster I think I can surely figure out how to do it correctly. But if I decide to do a narrow border, I will limit it to one inch or less.
Again, thanks for all your wisdom, ideas, compliments and encouragement! I appreciate your "second set of eyes" (multiple in this case) more than I can say!
