I would add a dark purple binding if I didn't have enough fabric for a wider border. Super quilt.

A beautiful gift! There's something about purple and green ... love those colors!

Lovely colour combo.

That's gorgeous! I really like those colors together.

Beautiful fabric. Love the pattern.

Pretty colors and quilt!

It's lovely and in that pattern! I do believe it has enough purples in it and may want to use a lighter color for last
Border so as not to lose any of the green border already when you add the backing to it.

It's just beautiful.

Quilt is beautiful as it is. I would not add another border and keep the modern look.

The colors are wonderful together! It's a beautiful quilt and I don't think it needs anything more unless you choose to add a border.
