Ok, I have finally finished the quilt top and am using a 100% cotton batting. The problem is I have no idea what to quilt into the larger triangles in the center of the quilt, since I know that it will have to be fairly close together. Any ideas?

how about stitch in the ditch. or maybe stitch 1/4' inside the lines all around and both sides of the larger blocks

I agree about going around the edges, but my problem is what to stitch inside that 1/4 inch edge. If I leave that open then after it is washed the batting will bunch and the stiches will not be close enough to keep a large clump from forming in the middle. The diagonal line is 12" across and both the 90 degree sides are 9".

Not sure but thought I'd let you know that the quilt is beatiful

Thank You! I was really nervous about the finished product because my boarder half square triangled don't have very defined points near the outer boarder.

What about a fleur-de-lis in each quarter of the center? The black and white just reminds me of clubs and aces - maybe the ace symbol?

That's a good idea! Thanks. I finally decided to just quilt an "echo" I think it's called. I'll post the finished product when it's complete. Thanks everyone for all your ideas.
