Print off your menu cards onto white cardstock and cut them. You can add your own text (font styles cannot be changed) in Adobe Reader, then print. Once printed, thoroughly rub your candle or wax crayon all over the heart shape. Make sure you go over the text properly because that’s the main part you want to hide.
Using nail polish, paint over the heart area until all covered with one thin coat. Much line when you paint your nails, don’t go over it again as it will look lumpy. Instead, let the first coat dry then go over with another coat of nail polish. You may need even a third coat depending on how think your nail polish is.
Let it dry and thy’re ready to be used! Just make sure you provide a penny, so guests can scratch off their cards.
