It seems we have all had an accident with a rotary cutter, and usually from not sharp enough. I will for sure, change the blade when I get back home this time. I , too am always tempted to just push a little harder. Mine got so bade last time it was like making dot to dot that I then used the scissors to cut apart. Maybe that would be a good idea to create a blade that did that on purpose, so we could take the fabric with us on a trip and do the cutting with scissors while traveling. Hmmm, maybe that's not a good idea either. Oh well.
