Silk purse out of a sow's ear?

This current project has me attempting a more tailored jacket, Vogue 8307, with , aakkk, fleece! I am not a fleece sewist but fell in love with this fabric when I saw it made into a vest at Fabric Fix in Manchester, New Hampshire. It kind of has the look of commercial carpet. You can see the fleece side in the photo as well. The color is a black and gold tweed that reads as rather grey and muddy. While Vogue 8307 is rather dramatic, this fabric got lost in itself and desperately needed some flash. I decided on piping the collar and opening in black patent leather. I am pleased with how the patent leather accents the drab color and the great lines of the collar. Here is the rub: The collar is faced with a black wool gab that was handy and rather lightweight. The jacket desperately needed topstitching to tame the "puffiness" of the fleece, so I have topstitched each seam on both sides. The color grey thread I used embedded and disappeared into the fabric and that was good. When I went to topstitch the collar, I had grey in the bobbin and therefore had nasty grey stitches on the black undercollar. I had planned on wearing the collar turned up so this definitely would not do. I also knew that ripping these threads out of the fleece would not work either.

In the night I had one of my Eureka dream moments. This morning I took a permanent black Sharpie and drew over the grey thread. Allehuhia! It worked like a charm. My grey topstitching is now black where it should be and you would never know it was done. Above is a pic of the undercollar. One side of the sharpie is grey. The other side is black. What little flecks you see there are the shine of the patent leather piping. On to the lining!
