Found these little words of wisdom on a lovely blog called http://bluebellandrosie.blogspot.com
Perhaps we should all take a minute to read this. Most of us are our own worst enemy, especially those who try to salvage a living from our "crafts", and when nothing is selling we (most of the time) think our product is "crap". We know that's not true of course, its all down to personal taste at the end of the day.
I can think of a couple of very prolific sellers on Folksy and I think "what's so special about their items?" then I see other sellers who are (in my opinion) excellent and they haven't sold a thing!!
I don't know the answer but these words do make you think!
