Such a beautiful quilt. I'm afraid I can't help you with the borders as I have the same the problem.

I think every quilt should have at least one border. Maybe a dark pink? Peggy

It looks great. I especially like the fabric you chose for the hearts.

That is pretty. I would go with pink border.

How about a key board of all the colors

I see bits of pink or an orange in those hearts...... so either color would really pop!!

IMHO, I think a thin border in the bright pink and binding in the dark purple would finish it off nicely. Love the layout and applaud your use of the leftover hearts. Thanks for sharing.

It's a gorgeous quilt! Nice job! :)
