Even after loading about 3 dozen bobbins with yarn, this very red linen cone still has 2 pounds 3 ounces for weight. The cone is plastic so probably no more than an ounce of weight for that, so essentially there is still a kilo of yarn left...
There is enough of the 2/16 red cotton to beam a 36 yard long 25"/section warp. That won't use up all of the red cotton, but I'm hoping I won't run out, either. Whatever little dribs and drabs left will get donated to someone who can likely use it. Any tubes with any kind of length left on them will be kept to use as accent in other warps. Or eventually given away as well.
When I was teaching, those tubes would be used for workshops. Now that I'm likely 'retired' from teaching I will either have to use those dribs and drabs up myself or pass them along to others.
It won't go to waste. :)
