Custom Armour trims

These custom armor trims would be like, once collecting or as  your collect the various armor trims, you could make your own armor trims, and custom patterns on the armor.  also perhaps like from other posts, the the armor trims could have some sort of effect depending on the armor trim.. i.e. netherite gives resistance, not too powerful, and other trims grant other abelites, or instead, these could come with the armor trims becoming enchantable, not the item armor trim, nor the armor with the armor trim, but the armor trim pattern itself.
