Yes, what IceBlossom said! Bonnie Hunter is a quilter and author in Virginia, and she has a youtube video showing how to "debone" a shirt to make it useable for making quilts.
"De-Boning" a Shirt! It has saved a lot of us some money and time in making our families some quilts out of clothes of loved ones who have passed away. One of my favorite things to do with shirts is to make memory pillows. The last picture is a quilt I made with some shirts that my cousin's late husband wore (I used Bonnie Hunter's deboning system to do the shirts for the pillows and quilt).
