By Monday (May 11) you should pick a pattern - preferably two! - choose and/or purchase your fabrics (don't forget to select fabric for binding), and then wash and press all of it.
A pressing tip: If you wish, use a little spray sizing to restore body to your fabric. You'll find that as you're learning to rotary cut, and sew your scant quarter-inch seam allowance, that little bit of sizing will add stability to the fabric, making it easier to handle.
Here's the "Noah's Ark" quilt I have begun for Mission Build West Virginia.
Please send me your fabric and quilt pictures!
