I'm interested in ordering a custom enamel pin featuring a minimalist logo design. The logo should have a slanted rectangular shape, tilted slightly right, resembling a parallelogram. I envision a smooth vertical gradient, starting with solid red at the bottom and transitioning to white at the top, with no text or additional symbols. Could you let me know if a size of approximately 1 inch (25mm) is feasible for achieving the desired gradient effect? Additionally, please advise whether printed enamel or an epoxy dome would be more suitable for this design. Looking forward to your input!
