Sorry if this is a little O/T for here, but has anyone ever cut their own slots to use up leftover bits? I've got a ton of useful lengths (50cm etc.) and the hallway is next to be done. I've made a few mistakes so will probably need another box or so, but it galls me that I've got all this offcut that just needs some ends cutting into it. This stuff is 10mm, I doubt I'll be able to replicate the "click" style stuff it has on it, but I just need to get them to interlock widthways as well as lengthways.
