In March I pieced and quilted this quilt for my son's 11th birthday. I had been saving his t-shirts for a few years but I had to raid his closet for a few more.
A lot of the shirts are technical shirts (uniforms and running shirts.) I did not have any trouble quilting any of them. I backed each shirt with the lightest fusible interfacing I could find prior to cutting down to size. I used a cotton batting and and a minky/cuddle fabric for the back. It was my first time using the minky and I did not have any trouble using it. I did notice that minky has a definite stretch in one direction. I quilted this with a geometric meander.
