Assuming this friend is a woman (shops at Michael's).
You should know better. You should read my book, "Man's survival in woman's world."
Rule #1: NEVER alter a woman's gift. EVAR.
Rule #2: The gift must be placed in a #1 location the first month. Gradually move the gift to a less discrete location over time. The target being the garage, or better a garage sale. When asked, just say "I thought the gift would look better there, as it naturally blends better with that room" (room being garage eventually)
Rule #3: The best way to stop the creative gift giving is simply to return the favor. Find the most manly things you can think of that you know she'll hate, and give it to her…Make sure it's not completely distasteful (like a nude picture or such). It must "appear" to look innocent, just make sure it reflects the typical "bonehead" men gift..It must be obvious and stick out when placed in a location and cause the sense of "gosh i really hate this, but I don't want to disappoint my friend" type of discomfort…….Make sure as you are giving it to her, you say "our friendship means a lot to me, and I thought about you when I got this for you.. I hope you proudly display this in a conspicuous location as a validation of our friendship". Don't forget to wrap the gift, otherwise she won't take you seriously. If you don't know how to wrap, pay someone to do it.
5) Dartboards….. And make sure that when she hangs it up, for the first month, you ALWAYS play darts, and you ALWAYS miss the dartboard, hitting the surrounding stucco.
6)Framed (and it must be framed and mounted) poster of your favorite car or motorcycle.
7)Ant farms.
8) Chiapet. Make sure you buy the ANIMAL/character shaped one, not the PLANT shaped one. For exampple, pick the Shaggy or Scobby Doo one. ALSO, make sure it's already grown (you grow it and then give it to her).
