Amy asked about my multi-stranded weft yarns - how I dealt with them, if I did anything special to make them behave.
Three yarn packages set up for winding. I always take off the end of a tube or cone. However, I always have the yarn feed off in the same direction. I use an electric bobbin winder which means I have both hands available to control the yarn. My left hand acts as a 'guide', my right hand fills the bobbin. By keeping the yarn feeding up and off the cones/tubes as centered as possible, the yarn feeds off evenly.
I have tried to use tubes laid on their sides and wound up frustrated with how unevenly they wound off, how the yarn would wrap around the axle holding the tubes, the jerking and uneven pulling of the yarn. Much better results to pull it off the end, imho.
Weaving. No, the selvedges aren't perfect but they are as consistent as I can make them. Perfection is for the angels. I'm far from being one of those! Slight imperfections in terms of yarn length will generally get taken up along the length of the weft pick. If there are large loops at the selvedge, they quite often just get trimmed off. With more than one strand in the weft, cutting one of the yarns isn't going to affect the integrity of the cloth.
And yes, that is probably a herd of dust buffalo on the floor by the yarn. I have free range dust buffalo...
