I can't speak to the contents of this book, but it caught my attention recently, and might be relevant to what your asking, so possibly synchronicitous: https://the3littlesisters.com/catalog_explorer/amulets-stones-herbs-runes-more/

It looks to be a guide for creating amulets/talismans from a mostly Heathen point of view, but seems also to incorporate natural magic and the like. I've gotten some good stuff from Gundarsson in other books, including some very detailed hands-on instruction for making things like hammers for blessing in the name of Thor or drinking horns or the like, so I suspect the "how to" in here should be pretty good.

Fair warning, though, the books I do have from this publisher are not as carefully edited as I would like, so it's possible there are some issues on that front as well.

Anyhow, hope you find something that helps, whether this or something else,
Jeff
