I am installing strand-woven bamboo flooring. One end is grooved, the other has a tongue.

Typically, I cut the tongue side to width and use that at the start of my row. Then I add a full-length board, and then finally the groove side of the board I cut.

My problem is: I've got a few boards where I mistakenly cut off the wrong end, leaving me a board with no tongue or groove on either end.

My question: what is the risk of using these tongueless or grooveless boards to start a row? (meaning I have two boards that abut and are not connected with tongue and groove).

Thanks
