start cut from inside like in this pic start cutting at the fold edge, its help, Cut slowly and several times slide your knife across the cut line.
the red line is NOT a line of cutting its shows only the edge on which I cut.
I see now thanks.
Well the inner side will be the easier one as it's more rubberish. I think I will spend more time on the outer side to make it nice.
Is there any way or trick to make the hole measuring easier or you just simple marked it somehow ?
