"Clue" challenge (from the board game "clue")
You will need the clue cards (or representatives - See below)
Each person picks one card from each of the three clue decks ("who", "what", and "where")
They will need to employ an element from all three of the cards. (Depending on the number of people in your guild that participate, they will be re-using at least some of the cards they draw - so have the members write their drawn cards down then replace the card in the hat for the next person. While it's possible for two quilters to have 3 identical cards, it's not likely given the number of possibilities, and even if there are duplicates, they will probably interpret them differently).
The quilter can be very creative with their interpretation of the who, the what and the where!! For example, Professor Plum can be the color purple, or fabric with plums on it. Mrs White can be the color white, or images of the White House. The Rope can be cowboy fabric with pictures of lasso's or a rope quilting motif. The billiard room can use the color billiard green or a block with circles.
If you want to make it easier ... have the quilters choose all three cards, but they only need to employ two of the cards in their quilt.
Some examples ...
* Mrs Peacock in the Conservatory with the Lead Pipe ... A Blue lattice quilt with a grey border (purple represents Mrs Peacock, Lattic represents the conservatory, and grey represents the grey in the lead pipe).
* Mrs White in the Study with the rope .... A bookshelf quilt (represents "study"), use book names that represent "white" (ie Moby Dick, White Fang - etc), and use a rope motif to quilt the line of the shelf.
