I think they're super cute! It shows that you really put a bit of yourself into whatever you're gifting. I like buying rolls of different kinds of ribbon, wired and not, and making my own decorations with them. I can't even tell you how much ribbon I have, haha. =]
Home made bows are AWESOME! It has tradition and it demonstrates technical proficiency if it can really shot!
But if it some sort of female technology for your appearance... like lipstick or something... then I am not sure... Don't all female technologies all seem the same anyway? Just don't tell people it's homemade or bought.
Cute! IF you know what you are doing! You can make some really unique, one-of-a-kind things in which you can be confident no one else will have the same! I say do it! If you are good at it you can always make a bunch and sell them online on a site like ETSY! (I make my own bows) :D
