Thanks all for the positive feedback!!!
I've improved my technique by purchasing a punch tool, since the freehand cut was the weakest part of my original design. After months of use, my own button has held up flawlessly.
That being said, I'm wondering if people would actually pay a fair price for this type of thing. I'm thinking $5 for a decal or $25 for a brand new button with decal installed--- plug and play. What do you guys think of that?
I came up with some additional design concepts I think are cool (and legal to sell). Take a look below. I'm open to new ideas or custom text.
If it is allowed by the forum rules, for now you could PM me if you want one--- if there is actual interest maybe I could start my own website and become a site sponsor!!! Let me know what you think!
