Yep, you'r right there Margo

The only variations to your project instructions I would add, is that alternatives to freezer paper are A4 (in UK), letter -8.5"x11" sticky labels. Or for smaller pieces of fabric, I have printed out the design on paper, then put double sided sticky tape at the top and both sides of the design, finally putting a piece of fabric, the same size as the taped box onto the tape, this ran through my printer just fine, but do make sure the edges are thoroughly pressed down.
