I guess it doesn't matter what the hobby or craft is, there are always unfinished products. I was never a knitter, but I did sew many years ago and had several patterns cut out and boxed, fabric, fabric scraps, etc...waiting for who knows what...more time, more patience, more creativity, whatever.
Finally, one day about 10 years after I had even sewn a stitch, when I was tired of opening, looking, moving, and trying to figure what to do with all this *stuff*... I pitched it all. I didn't even give any of it to the Goodwill. Just figured..who would want this *stuff*? Truth is, there was some good *stuff* there!
