i've done them both ways- i actually like the qayg method best- easier to handle them 1 block at a time- made my husband's step-mom a reversable one & made one of the granddaughters one that was put together (pillow case/birthing) method & tied instead of quilted-with fleece(minkie) backing...just because you are using t-shirts doesn't change the fact you can make it any way you want- still your project to do as you wish. i did still use )fabric stable-easier to cut, sew and living in Northern Michigan we like our quilts warm & lofty- so i always use batting...just my choices- make yours in ways that work for you
