I'd suggest keeping a small pot somewhere for you to bury whatever you need to bury. But in cases like this I'd suggest maybe making a small offering place, like a table or a box to keep them in. Remember that there is no hard and fast rules when it comes to your offering and the god/goddess would understand your situation. Pick an idea, if it feels right then go for it. It's probably the best one for you.

Hope that helps. And good luck and blessings on your new found path.

Various things. crystals, coins, anything really (within reason obviously). Basically anything you would give for a reason, like if you are doing a money spell then you would usually offer coins to the god/goddess, on certain sabbats things like holly, mistletoe, (don't forget to ask the dryad before taking it) honey cake and things (if they are perishable leave them for a while then get rid of them otherwise they will rot, so always explain why you are getting rid of it, simply obviously, but explain none the less, or bury them in your pots).

Try and make your offering in keeping with what ever the season is and whatever spells or rituals you are doing at the time. It strengthens your link to your deities and it also centres you better as well. You can leave them in a dish on your altar if needs be.

I hope that makes sense. If not just ask.
Blessings
