To be honest, I have not tried my hand at making things for Christmas (except baking of course), but my wife being a huge Harry Potter fan, I decided to do something with that theme this upcoming 2018 Christmas.
After failing to find any decent HP ornaments, I found a site that has a really cool looking glass (or plastic if you prefer) ball ornament for each of the four "schools". I will try to surprise her, especially if they do not turn out right, when we put up her 1st Harry Potter themed Christmas tree in the library this year...
