Ok, I admit it, done this before, several times.
1 I’ve learned that presentation is most effective when I don’t label the gift.
2 quality of the gift is important, get a good product don’t skimp.
They are more likely to get used and not kicked to the curb with the trash, besides everyone has parents and grand parents that might really need them.
3 wrap the gift with more than one layer, the inner layer should be a nursery/baby shower type paper.
You can even use nursery wall paper print, also the anticipation of the crowd grows as the layers peel off.
4 most important step, Don’t , Don't, Don’t say a word suggesting they open their presents.
Just not labeling the “gift” is not enough, you need to look as shocked as everyone else in the room when it’s opened.
5 purchase a second gift, a real gift that’s not related to anything AB/DL, spend at least as much if not more on the second gift, and make sure to wrap it totally different(put it in a gift bag). People look at the folds in the wrapping.
You don’t want to give your self away.
and last
6 never,never,never admit that it was your gift.
I’ve a few friends that still blame each other for my pranks.
