I have used the left over pieces (backs, sleeves, ect..) for the border. Sometimes I have enough to make the border all one color and sometimes the border is scrappy with different colors. Sometimes I don't use the left overs for borders - not enough or things don't look right. (I end up using regular quilting cotton for borders) If I can't use them for borders I usually just pitch the left overs

I would just go to YouTube and search making tshirts quilts. there are as many different opinions on how to make a quilt as there are people making them. You can pick up a little from several videos and use what makes you comfortable
