dublb - that quilt is beautiful. You must get it finished for your DSIS.
I had a real problem signing my BB. I found a permanent Silver Sharpie that showed up, but it did not come in a fine point. I practiced and practiced, but it just would not fit in that triangle. So, I resorted to the Ultra Fine Point Black. I know it does not show up very well, but it seemed to work better in the blue than the shell print. I did not think of the signature part when I picked out the fabrics. I was just concentrating on the shells, then the "water" blue. Took forever to find the fabric. You know when you have something in your mind as to what it should look like, it seems you can never find the right one.
