I am very new at cutting things out of leather and have tried with both a knife and shears to get a good straight edge when I cut out patterns and cannot cut a straight line no matter how hard I try. Normally it is the heavier leathers that i have the biggest issues with. I do not have a metal straight edge which is what I had supposed I could try next because cutting against a plastic or wood ruler doesn't help either. Any tips or tricks of the trade for cutting straight professional looking lines?
