So, many of you know that I recently found a set of twin quilt-tops with my name on them from my grand mother. They need to be quilted and being new to quilting, I wanted to try a few things on my machine before I finish the one's she left me.

-The first pic is my grandmothers quilt top.
-The second pic is of a small zig zag stitching in the seam. I have read that "on" the seam is just as acceptable is stitching in the ditch?
-The third pic is my first experiment with FMQ...Not happening right now!

SO...opinions of the zigzag? I can handle this. I think it will do the job without taking away from the thousand triangles!
