For teachers... these adorable yellow sandals with rulers on them! Maybe not the best idea for recess, but they're cool nonetheless.
For writers... these edible scrabble tiles. I can't vouch for the taste factor, but the idea is cute enough.
For the cyclist in your family... this ivy bike lock.
For your cool daughter, niece, best friend, whoever... this Orla Kiely bathing suit. Isn't this about as hip as one-pieces get?
For anyone heading out on their own... this custom stamp so they can make their own stationery and send you updates about life!
