I have a client at our office that asked me months ago about making her a t-shirt quilt. Then she ended up bringing me around 50 shirts so I had to pick 12 to use.
I'm not fond of t-shirt quilts as I feel they simply take too much time for the outcome. They look like you just sewed 12 squares together which I guess you did but it's hours of prep on the shirts before you ever get that far. Now that I finally have her's finished we're planning a second one in green. I even got the shirts prepped over the weekend. It was hard to decide what color to quilt it with. I went with natural as the maroon thread matched the sashing but looked terrible on the t shirts.
