Iteratively positioned and trimmed the baggage back carpet for better fit. Left it velcrord in place for now. Used paper and tape to line the baggage bottom area. Removed the lining and unfolded into a flat pattern. Iteratively applied adhesive starting with the channel top and positioned the carpet followed by more trimming. Its not perfect, but it looks pretty good and there are few open seams.
