10 year old nephew - $20 bill
For my sisters and two close female friends, I did what I always do and gave them gift bags with two or three little gifts in it geared to their tastes (fancy tea from Whole Foods, gloves, little decorative things, soap, shit like that)
Myself - a bottle of Laguvalin scotch
And that's it.
Years ago, I considered my dad very hard to buy gifts for, but now that I'm 42 he's easy. I just give him things that I'd like to get. It doesn't need to be incredibly useful, just something nice to have around. I'd love to get some fancy pens.
