I have to say that is quite amazing that you have reached this point in a day! Way to go. That is a great file and you did a beautiful job.
Like Elizabeth, I get lazy and tend to just lower the pressure on the machine when I have fold lines and just score with the blade I have in. If I can find a way around changing blades I will, even though I have separate blade holders for each (yes - totally lazy and want carefree adjustments!!)
Again, just want to say - GREAT job!!
