Print the mirror image of the design for the transfer.
Next cut out the image you want to use on your cake and tape it to a baking sheet.
REMEMBER to use the mirror image! Yes it is backwards but once you flip it over onto the cake it will be correct!
Cover the image with wax paper. Tape the wax paper to the baking sheet.
Trace the entire image and place the baking sheet into the freezer. Freeze for a few hours.
Remove the baking sheet and cover the design (carefully!) with a layer of white icing (or whatever color your cake will be!)
