I often see mountains of stash on youtube `influencers` the ones that do youtube after knitting or sewing for a few years. I don`t feel at all guilty about my stashes, in fact they are very good investments, if it can be translated into money
Everything in my fabric stash is catalogued and I have been slowly using the cheaper fabrics as toiles and have given away metres of quilting fabrics eg latest was 3m of cotton and steel.
I never make a song and dance about giving stuff away, I just bide my time until I see a need. It is karma. I have also recently given away most of my wood carving stash, to a community project
The fabric stash now is all good quality eg linens. If I want to sew, if I need a garment, then I look first at my catalogue, then the fabric and then I marry up a pattern. None of it will ever be wasted and I will never let any more of the fabric go. Toiles will go from my wardrobe but they are all well-made and other people can have them
My fluff stash is very good quality fluff eg cashmere silk blends. Fluff is the word we spinners use for tops for spinning. I had many good blends made in the old days and still have them, all away from moths and airtight. It is a slow process to get through my fluff stashes but spinning is a slow process too. I will not be buying any more and will not be giving any away. I also bought blends ready made from a Devon artisan, I like to support local companies. I am spinning one of theirs at the moment, merino/alpaca, very soft and for a shawl
My last stash is knitting wool, my downfall was not labelling some properly so now matching to a project is a tad more difficult. Again part in sealed vacuum bags and the rest in big sealed airtight drums
