So first I was wondering about making an alter to the goddess Juno, I have a few things I think will be good to put in there, like a peacock feather and I was thinking for offerings honey or burning herbs like lavender, but I'm new to alters and such and was wondering if anyone knows any other things that she might like.
Also with offerings like honey and wine, do I leave them there or do I take them and wash the offering plate, and how often should I do that every day? How long should I leave the offering plate there basically.
My other questions aren't about the alter basically I have a satin bag with some rose quartz, sun stone, a charm I got from a spell I have cast, a garnet and a diamond, its to help strengthen my boyfriend and my relationship, do you think that keeping it under my pillow and meditating on it while I fall asleep is good or should I carry it around with me? How well do you think the stones and bag work?
