Here is a YouTube (

My long armer said if you need to sew 2 pieces together to make it long enough not to use a diagonal line. Use a straight across seam to prevent this. I did use t-shirt fabric for the final border. The t-shirts I had was all different sizes so doing a straight set wasn't going to work for me. I will try and figure out how to do pictures and post one. Have fun with it and let us see your finished quilt.
