Over the last few days at the NEC many people asked about using freezer paper on the back of fabric before putting it through the BSC.
So, I thought I would try it and give you my personal opinion.
I have ironed the paper on with a very hot dry iron and left it to cool. Then placed it fabric down on to the standard mat and putting the pressure on 5 and the standard blade on 5( this was with a new blade...you may have to play with this depending on the age of your blade) and speed on 5 it cut beautifully. There was a little fraying but I guess that would be on the seam allowance.
I cut all the shapes from one of the quilt blocks and a circle.
For more complex shapes I would absolutely recommend that you use Heat n Bond lite if you wish to see through it and ultra if not.
I hope that helps
