Me again. I should have said you sew around the outside of the original sandwich to stablize it. Then you lay the next piece (front face down, backing right side facing the sandwich, and batting) on to the first sandwich. Sew 1/4 inch from edge. Flip the top piece over and bring the batting and backing to meet it. Stitch the open sides to close them. Then add your next piece. Most I have done were similar to a giant log cabin block. There is a you tube called quilt as you go Tshirt quilt where she is adding the last strip of blocks to her quilt and you can see how she does it. Nancy Zieman has shown this method on her show but I could not bring up any of her videos. When I do a T shirt quilt, I make strips 12"wide plus any sashing I have decided to use. I then join the strips using this method. After each strip is added, I do FMQ to outline the logo or writing so the stitching is about 4 inches spacing. I use a batting that requires stitching every 5 to 8 inches so My stitching ends up being close enough. Hope you can understand this method.
