I'm installing Pergo flooring and have come to a real problem. To finish up the area, I will need to reverse the way I laid down the first portion. I will need some "loose tongue" to get started again, but this is not something that's sold at any local Pergo dealers - I'm told it must be special ordered. Does anyone have any ideas of how I make my own or come up with an effective substitute. I don't really want to wait for a special order to come in.
