You all came up with such wonderful ideas, suggestions and starting points that I'm now feeling a bit guilty that I was a bit economical with the truth in my previous post. It is true that the house has just been finished and belongs to a couple I know. It is true that it was architect designed. It is true that they would like me to make a modern colourful quilt for the largest wall space. However, the couple involved are my parents and the house is about 18" tall. It was a birthday present from my Dad to my Mum and has been well over a year in the commissioning. It is what you might call a doll's house although it's more like a miniature architect's model than a doll's house since my Mum probably won't be playing families in it with miniature modern people. She will be furnishing it however and we are talking about a modern colourful quilt for the main wall and I really do need your suggestions. But I didn't want your suggestions to be limited by the idea of the quilt being a miniature and the house being a doll's house.
I am going to take the brave step into Pinterest which has completely baffled me until now and pin a lot of your fabulous suggestions. I'd still love you to keep the suggestions coming because you have shown me so many more things than I would have come up with myself. The finished quilt will be something like 10" x 18" and will be a proper miniature in the sense that I will design a full sized quilt but make it in miniature. For it to hang properly, I will need advice on whether to add wadding, what wadding to add and whether and how to quilt it but those problems are a while away for the moment.
So thank you for all your wonderful suggestions and please keep them coming. And for those of you who talked about looking at the house's surroundings, it will live in a bedroom with a Kaffe Fassett Diagonal Madness quilt on the bed so I guess you can imagine it set in rolling hills of pink, blue, orange, red, black, brown, yellow, purple, dots, swirls, stripes, flowers, leaves - well you get the picture.
