I hand quilt, and I will often take quilt tops to find stencils that fit in the blocks. For borders/sashes - I use cross-hatching, cable rope designs, or other linear patterns. I also try to balance curves w/ straight lines. If my blocks have smaller pieces, I just outline stitch the block - I don't like stitch in the ditch - too hard and I can't see it - If i spend my time quilting, I want to see my work.
