Making a grow grid DIY

Question

I've got weed membrane and want to add holes to it , like this. I don't want to buy them with precut holes as they're very expensive. 

https://www.quickcrop.ie/blog/2013/02/sow-easy-grow/

Need something very sharp able to cut 50+ holes like this.  I was thinking of using impact driver with that circular drill bit, normally used for fitting sunk ceiling spotlights... any ideas? doing it with scissors or knife is harder than you think.

Burn holes in so the fabric seals around the holes using a hot pipe (blowtorch plus metal pipe?).  Or four diagonal slits radiating from the centre.

I bought a weed burner (£17 with free delivery and 4 butane refills). Can't go wrong at that price! I will report back on how successful it is.

Seems to be quite a popular method with the yanks there are quite a few YouTube videos:

Great for tidying up fabric.  Say lay fabric underneath an irregular stone border and then just burn anything showing away.  Looks very neat.
