Best way to put up splashback

[tubeway]

I am about to put up a splashback in out kitchen to match the work surfaces. I do not have a problem with doing this - except that there are two awkward shaped items that will stop the splashback from being placed directly on the wall. What is the best way to cut out around these items ensuring a close a fit as possible - and a straight fit on the wall. The splashback is made of plywood about 5mm thick.

Any help is appreciated

Use a jig saw or a fretsaw. You'll get a better fit if you can take the objects off the wall & draw round them.

And use cardboard to make a template of the shapes so you can cut more accurately
