Butterflywing you had me rofl when I read your description of this quilt. I think it is just fine! If those are the colors your sister likes she will love it and more so because you took the time to make it for her :)
My sister loves brights...ugh...not quite my thing (although I guess looking at the fabrics I picked for my chicken blocks you wouldn't have guessed). Everytime I go to make her something and I walk thru all the electric blue, lime green, hot pink, whatever that orange and yellow that blinds you is called I just cringe and moan inwardly. :roll: I just put on my sunglasses and sew.
