Basic Black Cardstock is cut full width 8.5" x 8", with a score line at 4", so the card will fit in a No. 10 business size envelope (USA). (Or you can make your own envelope if you are so inclined!) The belt is 3/8" wide by the length of your 3 letters (you may have to trim to fit.)
A few hints for you - 1) Draw a light pencil line about 5/8" down from the top of the white paper to help you position the letter dies at the precise same height (use a white eraser to erase line before starting to place letters in frame you have created), 2) "Believe" will barely fit in the width of the paper, so be sure to layout the dies, so you can get the feel for how you need to space them when sending through the Big Shot, 3) Use wax paper to put between the snowflake die and the silver foil paper to help it easily remove from the die when using the die brush, 4) Use the liquid glue to assemble the hat prior to attaching with glue dots to the "B", 5) The 3 piece Belt glued prior to placing on the letters, 6) Attach belt with glue dots on the 3 "EVE" letters by laying the letters in the frame before attaching with the foam strips. . Then you can trim the belt to length if needed before placing the foam strips on the back of the letters.
