Your high school years aren’t exactly something to brag about. Sneaking out past curfew with Mr. Yellow Camaro, “borrowing” your big sister’s ID — hardly the stuff of heroic tales. But you would be proud if you were 18-year-old Greenhill High School senior Alysa Teichman, whose stationery collection, Alysa’s Friends, features artwork (a vivid peacock, stained-glass roses, serene scenes) done by four homeless artists. There’s a blurb about the artist on the back of each notecard, and all proceeds from the sale of the boxes of 16 cards (four of each design) go to The Stewpot, an outreach program for the homeless. Which means you won’t be the only one who’s glad that Teichman’s working to achieve something in her teenage years. Other than the award for Most Grounded. Available at Ylang-Ylang, 13350 Dallas Parkway, in the Galleria (972-980-0819 or alysasfriends.com).
