Bonnie hunter's strp twist
It is just sewing strips together, cutting, rearrange and voila you have a amazing secondary effect and also blocks with points. It looks way more amazing then it is hard to make and sews up in no time. I do second the lap quilt idea. 50-60 or 60x70.

Just be sure to pay attention to alternating light and dark strips but even if you don't it still looks good. Here is one I did mix up on the alternating light and dark but it came out nice. I bought some wild horse patterned fabric to go on the border to add a theme and visual interest. (donation quilt)
