If you really want to get your friends and loved ones something entirely original and creative, give some thought to visiting the Haven Collective at 938 State Street in the Upper State neighborhood of New Haven.
The collection there is mainly vintage, but there are also a whole lot of customized screen printed featured work in the front room, like this teeshirt collection from Jimi Patterson, who has received praise for his Joy Division album cover tee shirt idea from members as astute and observant as a certain managing director of a certain symphony orchestra.
Check out the whole collection. Here's a map in case you get lost.
