How should the metallic foils be applied to a desired surface?

Place the desired surface on a clean, sturdy, level work surface, face side up.  Next, position the metallic foil sheet onto the project surface where the design is desired; the matte side of the foil sheet should be facing upwards.  Once the Hot Foil Pen is fully heated, slowly write or draw over the foil sheet until the word, phrase, or desired drawing or doodle is complete.  Carefully, lift the foil sheet to reveal the shimmery embellishment.  NOTE:  It is always a good idea to test a surface first before creating an entire design.
