Now these two cat cross stitch patterns from the book The Cross Stitch Motif Bible: Over 1000 Motifs with Easy-to-Follow Color Charts aren't shown in black thread but I bet they would look awesome stitched in black. They would be a great Halloween project to dress up a plain towel, coaster or item of clothing.
