I made a set of Space Invader Christmas Tree Ornaments to send out as holiday cards to our clients at Cyber-NY. We had fun with all the colors and now they're hanging all over the office and are a favorite with my kids. Quick to print. Print in fun colors (mix it up). I was printing four-up with different bright neon colors for each. Then add a wire ornament hook to the hole and hang on your tree, on gift packaging or whatever.
