Hi grmamrtha1....the register tape keeps the strips from going wonky - as they would i'm sure if i tried to simply sew these bits together without it. Once done you can cut them to size and alternate with solids to make perhaps a rail fence quilt...or sew them into longer strips and alternate with a solid or white strip to make a simple scrappy quilt....or around a center solid square...whatever you like. If you Google - register tape scrap quilts - lots of other things come up, but there are more than a few of these types of quilts. Some have been pictured here on the QB in the past.
