I agree the quilt shop people are usually good with helping..What u can do is pick the colors she told u she wanted then lay them out..and then pick what u like for the other 2 colors..I personally think the corner pieces should be a light color..also have u thought of taking your grdaughter with u to help pick her colors..I have made my grdaughter wedding quilts also..and most of the colors are not what .I would pick..But I have found out that what I picked for the pattern..Does not always go with the colors..with teal and orange and yellow..u should stick with the brighter colors for the fan..otherwise the dark color will stand out too much..or if u do all bright colors for the fan..u could use black for the corner piece.That would make it very bright..That also would be pretty..many range of color for this..
