A worksheet that survives a copier
Most free word search downloads put a URL in the footer and a pale grid that dies on the second copy. These PDFs are built in the browser with jsPDF: black letters, letter paper, no site chrome on the puzzle.
The answer key is a second page so you can print one class set without handing out the key. If you only need the puzzle, print page 1.
Seasonal packets: fall, Halloween, Thanksgiving, Christmas, winter.
