Hi guys.

I've been using "Clear Magic Shrimp Foil" for the back of a nymph I created some years ago.

This may not strike you as a big problem but has been irretating me for a long time now.

The thing is that the strip is 4mm wide and 7cm long, it's too wide so I cut in half so it's about 2mm wide.
I have tried cutting it "the usual way" but also by rolling it up ad cutting the roll. What ever I try I get uneaven edges

Can anyone put me out of my misery and give me some hints here?
