Got two bedrooms and the hall between. A 15 foot hall with 6 doorways that had to be carefully fitted.
Gah!

And because the planks click on in a certain direction, when we got to the end of the first bedroom and entered the second, we had to start from the outer wall and work toward the mate-up with the line extended from the first: we were 1/4″ off, and the fix involved a rope snagging the whole floor and a lot of pulling, to shift the entire composed floor into line. Pix do exist. Jane has them in her camera.
