First gather up the t-shirts you want to use. It will take about 24 t-shirts to make a twin bed quilt.
Next decide on a common size square or rectangle based on the designs on the t-shirts you plan to use and make a template out of cardboard.
Lay the t-shirts out flat and using your template cut out your t-shirt tiles.
My tiles ended up being 11" X 14" which made a quilt of four rows across and seven rows down.
Sew the tiles together, then sew a backing to the sewn squares. I used a twin size cotton sheet. If you wanted this quilt to be warmer you could add a layer of quilt stuffing between the t-shirts and backing. We wanted a summer cover so I didn't use any stuffing.
Sew that tiles all around and on every seam so it is very secure to the backing.
Turn the edging over the raw edges of the tiles and sew to secure, making a finished blanket edge.

Now you can keep those favorite t-shirts forever!
