I just did a quick one...can't be for sure from the angle of the pic but it "looks" to me like a 4 loopers.
To get the 4" width, I used:
4.5" template (bottom layer)
4" template (top layer)
Wrap around till u have 4 loops on each side. Make sure when you wrap (or start wrapping), your other end tail ends at the bottom.
Now if it's a 3 loopers, just wrap 3 loops but I think that pic is a 4 loopers.
lmk if you need pics.
