@Roidsey TBF in this situation I found it easier to simple use up off cuts & put in 2 pieces. Though using a bar to scribe one end, mark the tile both sides of the bar & then scribe the other also well Definitely sure you knew that already tho
@MGD-Hygiene This is only an example of the technique You can use anything from a piece of scrap to a tab box Personally I mostly just use masking tape
