Threads like this one are why I keep logging in. Helpful and constructive truths that are also wrapped in camaraderie.
To the OP, don't be afraid to fail when making things. We all have scrap boxes with rather interesting and/or ugly cast offs our mothers wouldn't compliment. Also, don't be afraid to laugh and shrug it off. Continually improving your work will get you to a sellable item. It may not be tomorrow or even a month from now, but at some point if you are diligent, you'll see something after you finish it that is worthy of being sold. That said, also be prepared to spend your initial setup costs without a means to pay it back for a good while. I have a thousand or so dollars into this and may have sold $300 over the last few years at a hobbyists pace.
Patience and welcome!
