Put it under the tree with a tag on it "From Santa" he will know where it came from!!! If you have no tree up this year, put it in his favorite chair....and don't say a word!!! Or you could tell him in advance that you made him something with love...and if he is so inclined he can make you something or go purchase something small in return so he doesn't feel bad.....but we all know that that isn't what it is all about...or you can hold it till his birthday, anniversary, Valentine's day....whatever!!!
