Oh, I just love red pepper quilts- the COLORS! she uses especially. I like her stitch in the ditch on both sides, too. It looks so professional or something with it being on both sides.
I vote no borders on this. It looks complete as is.
This quilt is on my to-do list- I love zigzag quilts and NO HSTs! I want to make a Christmas one with bright white, lime greens, dark greens, red and maybe one bright pink zigzag. Yours is gorgeous in these "normal" colors, though, so maybe I need to make two of them- one for most of the year, and one for Christmas.
You did a really good job!
