Here is my method, not better than others, just my way.
I cut out the t shirt fronts over sized and fuse whatever fusible I'm going to use before cutting out the finished square. That helps with keeping the stretch at a minimum. I use the tricot fusible, just making sure that the "stretch" in the fusible goes opposite the "stretch" in the t shirt. The tricot makes for a softer product. I than do a large stipple over the entire quilt top when it is pieced together.
What ever method you use it will be beautiful!!
Happy New Year!
