Claire, whose summer reading regimine has included the first two (working on three) Harry Potter books (she's happily somewhere in the middle of The Prisoner of Azkaban even as I write), among others, designed this t-shirt inside her head last week, and told me about it.
So we went to Jo-Ann (fabric and crafts store) and found the light pink t-shirt, the flocked black iron-on letters, and the iron-on glam heart, and voila! :)
ps I accidentally ironed the "N" in Hermione on upside-down. Rather than "a mistake," I like to think of that as "a mother's loving touch". Ha.
