Well, I came up with about a 14 way stretch.
The first six or so are what some might do with a kicker to hook before stretching. I can't kick, ask my 30 year old hernia.
I use a kicker to nudge carpet onto the tackstrip before my initial stretches, but in this case I wanted more oomph during the initial hooking. Some stretches were done twice, especially the last angled one.
I stretched hard into that angled corner, then angled the two longer walls towards it, which loosened the angle wall a little bit, so my last stretch went once more into that short angled wall.
It seemed to be stretched really tight and even.
The long walls are about 9' 6", the angles 5' ...ish. the rooms about 17'6 by 17'6"
...........could you imagine the stretching this room with a bed and furniture
......it ain't a happnin' buddy .
Woulda been a lot easier without that metal staircase.
Anyway here's the progression of the stretching.
Not sure if it makes sense....
It does to me.
