Hi, MM,
This is a tough one! How to get people to agree? Yikes! All I can think of is to set a definite deadline, a date that you MUST make a decision. Maybe that will force people to quit wavering.
Could you start by deciding what colors you want to use? Then maybe moving onto a design? Or at least find two final choices and then take a vote between them?
Good luck! I know what you are going through. My club did this a few years back and it took quite a long time to agree on what to do. We finally did and everyone ended up pleased. Now we are beginning to think it's time to do another idea.
Keep us posted on how it goes.........
