@Solasta_Amore and All:
If you plan on burying your bottle maybe consider using a toliet paper insert or papertowel insert. Just fold the ends in and its perfectly biodegradable! 
The folds can be like half moon shaped too 
There was a post about it with @silverbear in the forum. Silverbear also has many spell jar recipes and you can find her in our forum, on youtube and instagram I think.
Like silverbear and @Artemisia I have a love of jars and containers like wood boxes, cardboard boxes, even some plastic but I only use recycled plastic items for my craft.
Hooray for the spell jar challenge! Sooo much fun to feed our obsessions
