I used Sew Memorable Quilts to make one for my daughter with her high school t shirts. My sister found her in her hometown. Lisa, owner, is amazing and very reasonable. She was half the cost of someone in my area. I sent her the shirts and she emailed me color swatches and the quilt turned out beautiful. It is truly a small world as I found out that she is friends with one of my sorority sisters! here is a link to her website:
