Re-creating a cross?

Does anyone know if it's possible to re-create a cross in order to remove a warp from a loom and re-warp it later?  I put a basic warp on my Gilmore loom for a friend to practice with, but want to remove it so that I can start a different project.  It's 3 yards long and 12" wide, so I don't want to just trash the fiber. Thanks!
