I think a pretty lilac sashing would work well. And, I think I would arrange blocks a little bit differently putting the larger ones in the Center row to kinda balance it out. Good luck with it. Please post when finished.

I agree with sak658.

I think shashing would be really nice.

Well someone loves the latest arrangement

I would sash with green, put blocks on point, purple setting triangles and then small green inner border and bigger purple border. Just my idea to make this "sing!" Can't wait to see this finished!!!!

Be careful about cutting blocks down to a common size. I had a similar set of blocks made by my guild members. When I squared them all up, it cut off the points on some of the blocks and that spoiled blocks that would have been perfect at 1/2" larger. Better to add some sashing in different widths to get the blocks all to the same size than to cut them all down. There is nothing that says it have to be absolutely symmetrical :-)

How about a sashing that makes small stars in the cornerstones???

I vote for small sashing.

I agree that a narrow sashing would be best. Congrats on receiving so many pretty blocks.

I would go with a dark purple sashing to offset the various block designs. Please show us the finished quilt no matter what you decide.
