I have a good friend whose niece had a baby a year or two ago. She was concerned as to what to send as a gift, because the niece is very wealthy, and runs in wealthy circles, etc. My friend knew she couldn't afford a gift of the caliber of other gifts that could be received.
I suggested she crochet (she's not a knitter) a baby blanket for her neice's baby. She felt that her niece, and niece's mom (my friend's sister who is just a tad snooty) might find it pathetic. I assured her that, as her blankets are beautiful, and the fact that it would be a handmade item from a beloved aunt, it would be appreciated and well received.
She did crochet the blanket, and sent it. The niece literally gushed over it. My friend's somewhat snooty sister also gushed over it. My friend was so happy that she'd decided to do that.
Do your relatives live in cold climates? Maybe you could make scarves for the ladies, and caps for the guys; or even scarves for the guys, in manly colors? If so, be sure and include some sort of tag indicating the item is hand knit by you.
