The Festival of Navigation (Navigium Isidis) was an ancient Roman festival that celebrated Isis as the ruler over safe navigation, boats, fishing, and the final journey of life. At this festival, after an elaborate parade, a Ship of Isis filled with great offerings of incense, flowers, libations and small shrines was sent out to sea.
I do like the idea of sending out ships with offerings to Isis. And with that in mind, I'm sharing here a video tutorial on how to make a paper boat that floats on water. This small boat could be decorated with symbols or with petitions for guidance, filled small offerings, and then floated down a stream, creek, river, etc. If you don't have access to water, you could ritually burn your boat on a bed of incense and fragrant herbs and allow the smoke to take your petitions and offerings to the goddess.
