I've used the following steps to make this altered puzzle.
1. First of all I've bought myself a very cheap puzzle with the number of pieces that's just right for the numbers of members in the COF.
2. Then I've covered the pieces with the colour scheme that I want to use for my project. Use a thin card stock for this step.
3. Start decorating each pieces individually.
For the complete look of the project, you can refer to "Altered Puzzles Addresses" in my others gallery.
