This one feels like a little bit of a cop-out, but I wasn't terribly inspired by anything that came today. Daily Candy did have some fun Mother's day gift ideas, so check that out. But the age range is not so much for my mother, but rather if I were to be a mother myself... I particularly liked the knitwear espresso cups (if only I drank espresso) and the pillows with pockets for your cold fingers or toes. Clever.
There were some other fun things there, and one linked me to this online store - greenergrassdesign. It's kind of like going to the museum gift shop online - they have all the cool stuff in one place.
Check it out - might be more for your friends than your mom, unless you have a super hip mom, which someday, I hope to be.
