Even though my sewing machines have cutting blades on the left hand side I don’t use them because as a right handed person I want to reach for my scissors, instead. 

I’ve found this simple way to keep a small pair of scissors nearby on each sewing machine (I have 4, but three are on my sewing tables). 

Plastic hooks with removable tape on a clear spot on the side of the machine does the trick – once I got used to not having to hunt for scissors when I’m sewing I no longer have to think about it – they’re always right at hand!
