Gls - when printing, there is a box to check labled "size from quilt"
tyme - yes it is Glad press and seal. I place it on my pattern and trace the block. The cut it apart with a craft knife and use it like I would freezer paper. It is clear so sometimes hard to see, but when I am doing curves, it is flexiable enough to stay on the fabric while I manipulate it. I probably get a better result with freezer paper and tracing the sewing lines, but when I have the kids around and want to do a block, I pull out this product. No iron necessary. I have also used it for Hand quilting templates. Cut my shape, press it to the quilt, and stitch next to the edge.
I've had Press and Seal stretch when cutting it apart, so use caution. Some scissors do not like it, so I used a ruler and craft knife. Might even try pressing it to scratch paper and cutting it while affixed.
