J0`Ann's has some not sure of the
name -but back by the outdoor canvas is a UV specialty thread. I bought Fire Resistant thread to sew a neck /face cover for my nephew for his race suit was on the same sort of thread, heavy textured just used a jean needle I've redone three awning tops plus a few pillow cushions over last couple years and fixed -patched a winter cover for a 45 foot RV. Talk about a challenge Good luck :)
