I know you have a deadline and I agree with Illinois, you might not want to tackle an intricate pattern for this with time being so near. Have you thought about a Chevron pattern for the quilt? Those colors of grey and burgundy would look cool and you could use the burnt orange as an accent in the binding, perhaps as a faux binding. I made my son a black and white quilt with a pop color as our groups challenge quilt one year and used the burnt orange (he is a Texas Longhorn die hard fan) as the faux binding strip, turned out great. Missouri Star has a quick pattern for a Chevron, as does Jordan Fabrics.
