I hope you don’t mind that I made your question its own topic for visibility & replies maybe being more in-depth.
We have a few discussions about this topic in the forum. From small wooden boxes to an altoids tin, it’s possible & all you need is what you think you would use away from home.
- candle
- matches/lighter
- crystals
- common herbs that you use
- whatever would make you feel comfortable on the go for a quick something in whatever size you would need. So keep in mind where you will keep it & use it. You could use a small box if you were keeping it in your glove box or an altoids tin type container for your purse.
It’s really all up to you. But for more inspiration:
Making a Travel Altar
What is the best way to set up a Travel Altar
There are some starter posts, but there are more within the forum & other members may have some ideas that they currently use.
I personally do not have a travel altar. So I can’t give you any other tips than I already have. I hope they help!
