just one shape. the 'triangles' are squares with a diagonal gradient and one half white C]:0)
Can you not guess who 'J' is . . . I'm sure you know them
EDIT: Also, The design isn't mine, it's from a cross-stitch. I hardly ever create . . . only copy
they might be squares, but they're squares doing a great impression of triangles
and, erm, no - i know who TLH is, so i'd have understood an H, but not J ? (:
