You can also score (not quite cut completely through) and then bend and snap plastic for straight cuts. For intricate designs, I'd go with a #11 Exacto style blade and be careful.





Use hardboard or something not too soft as a backing -- too soft and the plastic will bend and deform. Also, depending on what you're cutting, you can cut a little outside your guidelines and then sand to exact shape/fit.What's best for cutting thin sheets of plastic?

Have you tried an exacto type knife?

for straight cuts a straightedge and ';sharp'; Xacto knife


on a solid surface to prevent deformation of your plastic


some modellers use a piece of tempered glass with the edges rounded


as the knife won't damage it


for intricate curvy cuts great care and patience as well as a sharp knife
For sheet plastic that thin, I'd use an Xacto knife with a #11 blade.
