If you wanted to learn the art of gift wrapping, wouldn’t you want someone Japanese to teach you ? Paper Tree, the origami store in Japan Town, is offering a 1-hour class this Saturday at 9:30. $40. While you’ve got a few hours reprieve from the US Postal Service why not make your own cards? Here’s an online class to guide you. For a gift that will come in handy during winter power outages, make your own custom scented soy candles at ThnkBox Studios in the City on Wednesday, December 21. $65. Speaking of holiday spirits why not improve your bartending skills at a Mixology class at the Infusion Lounge, downtown. $79.
