My favorite freezer paper is made by C. Jenkins Company - it's very sturdy and can be used over and over. (In the long run, it's a real time saver. I cut a generous 1/2" seam allowance around the template pieces.)
The pattern template is pressed (dry hot iron) to the wrong side of the fabric - the fabric piece can easily be positioned for stitching. (I remove the template before sewing.)
The pins also keep the fabric in place. I don't know about you, but my fabric has slipped out of place when flipping the piece over - I HATE unsewing!! - using pins, I have had no problems with slippage.
A tool I find useful is a wood folder - it give a really good crease to the paper which will make removing the paper later much easier.
finished block cut to size and ready to go!
