There is a ruler that uses strips of fabric to cut the triangles for on point quilts. It does 19 inch blocks. It is the EZ Flip and Set ruler. If you do a lot of on point quilts it's worth the money.
Oh, I just re-read your post and the light came on (grin). You want a pieced block that you can cut into the triangles and quarter triangles for the ends of the rows..... Most that I have seen are appliqued or a pretty patterned fabric. Good luck on your adventure and let us see your results!
