My strippy quilt is made of pinks and greens. One green strip is the first strip down running "almost" diagonally. Many are off "kilter". Half of the greens are from upper left to lower right; the other half are from upper right to lower left. Then when set, the greens cause "Xs" or "Vs". The balance of the blocks are in many, many pinks of different widths. (There is only one green per block.) -- Saw this technique on "Simply Quilts".
I used old fabric as my base cut larger than needed and then squared up when done. I didn't use a batting. It is tied and used as a summer quilt.
