each one has a specific story, purpose, and ritual, research them all, but the next one is Beltane, so focus on that one, then move on to the next as the wheel turns. [For Beltane my coven usually has a picnic] its a celebration of the God and Goddesses wedding, so think about wedding parties and what emotions surround them. [The good, not the in-laws fighting] its also a time for young lovers and many have their handfastings around this time. Dancing around the Maypole is another common activity [though how many solitaries own one of those?] I personally feel Beltane is one of those you should celebrate with others, so if possible try to throw a party, or look into a local gathering on that day [if you are aloud to attend, I don't want to tell a minor to go hang with strangers after all]
If you're by yourself though, go for a walk in the woods, speak with the Lord and Lady, make them a wedding gift as an offering, stuff like that.
