Where do your other skills lie, what do you feel most comfortable doing?

Mason/glass jars are pretty cheap at Kmart or at the op shop if you have a dishwasher to run them through to sterilise them.

You could do those hot chocolate mixes, the ones made as gifts where the different ingredients are layered attractively inside the glass. And tie a reusable ribbon on. You know the ones. https://youtu.be/jf23otl9ztE This is also a thing with biscuit mixes.

Tiny terrariums would be simple but I hear you need a dedicated pan or baking tray to bake the soil or potting mix in (to sterilise it against unwanted nasties growing in the sealed container) and it can make your oven or house stink.

There is the method where you pour boiling water into the soil and cover with tinfoil to retain heat, but while I haven’t done terrariums to test this I don’t think it would be thorough enough for a sealed container.

You could make hot chocolate spoons with disposable wooden spoons and wrap them in cellophane and a ribbon like a lollipop. (Basically you dip spoons in melted chocolate and then a decoration like sprinkles or add mini marshmallows. For bigger serves others fill ice cube trays or muffin pans with chocolate and stand the spoon in it and add marshmallows on top. The idea is you stir hot milk with the chocolate coated spoon and the chocolate melts to flavour it, and releases the marshmallows.)

I haven’t made fudge or coconut ice but that could be a go. You could even make two different flavour batches of fudge and marble them together decoratively, like a peppermint chocolate marble fudge.
