This is a PDF file with 12 printable pages. Each Flash Card set includes 26 cards with the same 26 colors. There are two front/back pages for each card set. (1)Print and cut white border around cards. It makes it easier to line up front and back images. (2)Glue one side of front/back. (3)Line up corners and stick pages together. (4)Cut and laminate. I've been making flash cards and card games for my son for years. I'm new to TPT. Feel free to comment on format or any other suggestions.
