I think that they were not sewing up the holes in the tent, but the holes in the shoe covers.
As we know, Lyuda Dubinina bought 5 meters of cambric with the money allocated for the hike (200 rubles from the hike project).
It turns out that each one is half a meter high, like the height of the boots, and the width of the roll is equal to the girth (one and a half or two meters).
Dmitry Kireyev from Serov told me his vision that Zina Kolmogorova cut shoe covers from this fabric at a school near the train station in the city of Serov. This can be seen in the last photo on film #2. Since cambric is a fragile fabric, there could be problems with it.
Therefore, all the tourists were angry and Lyuda hid in the tent.
All the others sewed up their shoe covers while sitting by the fire.
It is hard to imagine several people spreading out inside or outside to sew a tent. One person is enough for this job.
To Z. Kolmogorova also belong: vigogne socks almost black color (tinted), white woolen socks, mended tarpaulin, mittens wool blue brown pattern, cotton, blue ski gauntlet gloves ("Краги" - russ.), dark brown woolen gloves, mended tent cover (old), home cloth slippers, new, on the sole outside herringbone pattern.
Ladies quilted jacket with artificial dark brown collar with a rubber band at the bottom and fastened hood made of blue satin. The show covers are made of decorative cloth (in the form of bags)
