Mind you, I'm no quilter, so I probably did 101 things you're not supposed to do, but all in all I'm quite pleased with how it turned out! I was given 30 shirts and used all of them (most had images on both the front and the back, a total of over 50 squares each measuring 15.5 inches). I stabilized all the knits with ultra lightweight interfacing (a Black Friday doorbuster item at JoAnn) and backed the entire thing with a pretty purple geometric-print flannel (also from JoAnn on Black Friday). I didn't get a photo of the back (lucky to even get this shot!), but there's also one row of t-shirts on the back. The couple I made it for is giving it to their daughter for Christmas. Isn't that a wonderful gift!?
As much fun as I had sewing it, I'm so glad it's done. I love meeting (and beating!) a deadline. The euphoria and sense of freedom after completing a big project is exhilarating!
