Cutting cardboard in straight lines with scissors is easy, but cutting convex curves other shapes is really not, especially if you want to avoid bending it and collapsing the corrugation. Personally I use a knife, but obviously that isn't suitable for very young kids (not hugely safe for me either lol, I almost cut the end of my thumb off not too long ago...)
- parpfish 1y agoIf convex curves are too hard, just make a concave curve and keep the other side.
- xattt 1y agoI am not sure if this is board stretcher-level pranking or actual advice. Bravo!
- WillAdams 1y agoThe problem of course is that often one side of the curve is mangled/distorted from fitting the tool into it --- guess which one it usually is?
- junga 1y agoIt's always the side you want to keep of course.
- istjohn 1y agoConvex curves can be approximated by a series of straight cuts tangent to the desired arc. It's concave curves that are difficult.
- Retr0id 1y agoAh yeah, I meant to say concave.
