Good morning Cissyquilts......I just saw your wonderful GFG. You are so lucky to have it. If it were mine, I would not wash it before quilting. After looking at the back, it seems some of the seam allowences are perhaps a tad less than the usual 1/4 inch, and I would think it might ravel some. If you do deceide to wash it, I would do the bath tub method as recommended here by some of the other ladies, and perhaps cool water. Good luck in what ever you deceide. It's beautiful!
mgshaw........your siggie blocks are also beautiful. It surly would be nice if you had some history on those ladies. Don't you wish we could go back in time and visit with them!?
