1. Wrap Santa's packages in special wrapping paper . . . and then destroy the evidence
Don't even dare use the same green holly wrapping paper on gifts from Santa as you do on gifts from yourself. It's best to buy a roll of paper reserved for Santa alone, or use brown kraft paper cinched with twine for a more authentic feel (because why would Santa use store-bought trimmings?!). This might seem wasteful, but donate whatever unused wrapping paper you have left. Nosy kids might discover the remnants of the roll in the back of a closet months from now, and you'll have some unexpected explaining to do.
2. Use different handwriting for Santa’s presents
It's a rookie mistake to sign, "Love, Mom and Dad" in the same handwriting as "From Santa." Try using your less dominant hand for Santa's signature, or if it's too hard to fake, enlist the help of someone else, or perhaps Santa can have sweet printed tags on his presents! Also, don't forget to switch up the pen you use!
