Hi Lanzalady, I haven't got any rituals, but one thing I am hoping to do is make my own mini Maypole to put on to my working area.
I have the ribbons and the paper flowers-(I have paper flowers instead of real as I like to see the flowers grow in the wild) Now i got to start looking out for a stick that is already on the floor (this will make my pole). I just hope it works out as it is my 1st real maypole.

You could make a head wreath made from flowers and even ribbons-greens, yellows, blues, pinks etc. and wear it for your workings on mayday or wear just for the day of May.
And if you can light a beltane fire or just light a candle that's another thing that you can do.

What ever you do, I hope you will enjoy it and have lots of fun
Best regards & Blessings!
