ha!!! i bought those same jelly roll fabrics.
i had some batik charms that i added strips to so they would be a larger block. sewed them all together and added a border. Still had those strips left over! so i took two blocks that were extras and added strips until they make 20 inch squares. large enough to be a pillow and the quilt top will now be a "Quillow".
still have some strips left over though!! hmmm.i may add them somewhere in the backing.
some of the strips were difficult to stitch through. my needle went thunk,thunk through those. pink and the teal ones and then the border fabric i already had.
maybe that was the dying process that caused that.
