I think there is a lot of us who feel the same way sometimes, I have invested lots of money in wool so that i can make my products for my shop, I have made sales but I have at the moment reinvested the money on a new sewing machine, knitting needles, cotton, lace etc. I, at least am prepared to do this initially, and am hoping that this will pay off in the long-term. I tried a business back in 2009 and failed miserably, mainly because I didnt want to keep investing. This time, it is working out for me at the moment, between Etsy and my wednesday market stall, it is finally beginning to pay off. I wish you luck for the future, stick with it, i am sure that it will all pay off, with a little patients and a lot of self belief in yourself and your product
