I think I missed something. Was somebody recommending plexiglass as a way of seeing where your placement would be when you cut out the shirts? I have an easier, cheaper way - use a piece of cardboard. I determine what size I want the t-shirt blocks to be, mark that on the center of the cardboard, and cut out the center with an exacto knife. This makes a cardboard frame. I center that on the t-shirt and mark where my cutting lines are. It's easy to do, the frame is reusable, and I don't have to go through the expense of making a new plexiglass template in case the block sizes are different from one quilt to the next, or if I want to use multiple sizes of blocks in my quilt.
