I wondered because the rotary cut list by block is on the disk.... but I cut out the templates and cut my fabric to do the pp...so I do not waste the fabric. I think it allows one to cut the fabric to size to do the templates, not sure. I think your results and mine end up about the same...and achieves the same purpose.
In our own comfort zone!
I gave tried to think up a way to cut each block out and 'bag it' with the notebook, but have not found a good way of doing that yet., other than trying to put them into the protective sleeve and that 'bugles' the sleeve out too much and causes it to spill out.
