did you see the"manly" quilt that Eddie made ?
It's somewhere in the picture section.
How about plaids and stripes?
The "manly colors with a feminine design" would throw me, too.
Maybe she's talking about the fabrics, and not the quilt design?
One could go with the fall palette - or patriotic (red, white, and blue) - patriotic might be different colors for different countries?
How about having her go shopping with you for the fabrics? Or at least have her say "This would work, etc." - until you have a pattern picked out, you may not know amounts to purchase
