I would echo the other comment...you will get much better participation if you plan a project that everyone can participate in...the whole mystery quilt thing sounds good but then they start wanting you to spend money on supplies that you have no idea how are going to be used or how many other colors, tones, shades, etc., you will need... it makes people drop out by the droves.... just my 2 cents...i hope the project turns out well whatever you decide...
