Spooky Book Mom Line-Art T-Shirt

Create a centered t-shirt design featuring a line-art style with a playful, hand-drawn aesthetic. Include spooky doodles like haunted books, ghostly glasses, bats, and pumpkin mugs for a book mom. Centered phrase: "Behind Every Spooky Day Is a Creepy Chapter". All elements must be clean white line-art only with no fill, optimized for printing on dark shirts, with a fully transparent background.
