Give me a reality check, is my design too dainty?
I make fidget rings like this. These "charms" are basically hold by 1.5x0.7mm (thickness) jump rings in D shape (as the ring bands is half-round). I handmade all of these and always use hard solder on every joints. Someone ordered this ring 2 months ago and told me today the flower simply failed off and claimed it was structural faulty. The flowers always have a flat base and the jump ring is also filed slightly flat at the top to attach better. How can I improve this design? Reduce the size of the flowers? Make the jump rings thicker? Or do this one entirely different?
