I am making this t-shirt quilt for my DIL from her high school t-shirts. The measurements are 72 X 86 without borders. The first question is...should I put on a small border or just stop here??? I also have another question...what color of thread do you think I should use to quilt it? I am just going to scribble (meander) to quilt it but not sure what color I should use??? Any ideas would be appreciated!!
