When I weave Shetland wool blankets, I plan on seven blankets for a project. This works out to 18.5 turns of the back beam when warping. (My counting is generally more reliable than the yarn meter on the tension box; if the yarn slips off I'm lost, so I now just count aloud.)
For the 15th batch of Shetland wool blankets, I added an extra half metre and knew it would be plenty to weave one extra-long blanket at the end of the warp. Correct - this one is 2.8 m long, which is over 9 feet.
