Color really is so personal....I can't imagine myself putting red and purple together and so many of you suggested it! To me they just don't "go"! Obviously this is a situation where there is no "right" answer, it "just depends"!
If it were MY quilt, I would probably go for a soft lavender. But now I'm super curious to see what red would look like. Maybe I've been missing out on a great color combination all these years!
I will be watching to see what you do with this...I like your blocks, they look very precise! I'm sure it's going to turn out GREAT.
