No costume? No problem! Heres a printable Clefairy (Pokemon) mask which you can use in your childs party (or maybe make it part of their Halloween costume). HOW IT WORKS: The mask is set to size: You will need to print the PDF on an A4 or 8.5 x 11 inch card. Print file at 100% with no page scaling. (One mask per page). Print one first and see if it fits perfectly, if not, adjust by scaling. Cut out the eye holes (black part). Make a small hole on each side of the mask and attach elastic.
