Chris- They are beautiful and a fine piece of work to be proud of. But as somebody who got started 5 years ago as a toy maker, I STRONGLY encourage you to become thoroughly familiar with the CPSIA and the laws surrounding anything for children age 12 or younger. Simply saying they are only for decoration would not keep you safe from the scope of this law and the CPSC.
I stopped making toys because of the mandatory testing requirements under this law (not because my toys were unsafe, I just couldn't afford the required testing to prove it).
You my want to look into the Handmade Toy Alliance. I was a founding Board member when it first was started back in 2008, they are a 501c6 tradegroup and are in close contact with the CPSC. They can direct you to the latest updates regarding minimum width, lead content testing, use and abuse testing, etc... Additionally, baby rattles have even more guidelines that must be met not only because they are often chewed on, but also because of the tiny "things" inside that may be swallowed should it break open when baby smashes it on a tile floor while Mom or Dad aren't right there to pick up the pieces. The fact that these have washers in them worries me (as a parent) and should worry you (at a minimum as the business owner).
Sorry to be the downer in your thread. All my best.
