SuzzyQ ... comments from the Ontario Peanut Gallery .... first of all where did you get the black and green fabric? (hoping I might score some too!)
Going back to the earlier comments and now that I see it worked up, I think that blue/green plain works It works well with the white and the green/white print, but IMHO not with the black print or the lime. I really like the black and the lime together ... a perfect fit.
Not knowing how much of each fabric you have ... perhaps you could solve that by doing smaller finished items?? It has been my experience at auctions, that all too often a larger item people do not pay the "value", yet smaller items often go over valued, as people are willing to pay for the novelty of it, and to support the cause.
And ................ the Ontario 4-H crowd can really get into overdrive on that, especially if someone decides to goad a colleague on!!
Smaller is Better!
