I did a search using Google but couldn't find any black in the Sunstreaks. I did, however, find a Patrick Lose black that is fairly close by going to

Search for "Patrick Lose" and on page 2 the second fabric from the bottom, would that work in lieu of? It returned apprx 20 pages and I didn't go through just the first three or so.
Good Luck!
