The people at Creative Ardagh say this about the Brigit's cross tutorial they've posted on YouTube:
We are located in St. Brigid's parish in Ardagh. Each year locals and others walk down to her holy well near the village. Connections to the saint locally go even further back. As a daughter of the Dagda, the pre-Christian Brigid is a sister of Midir. St. Brigid's Day/Imbolc is celebrated the start of Spring each year in Ireland, 1st February. Rose Moran reads her poem Brigid Passes as we give step-by-step instructions to make your own cross. Thanks to Rose and to Martin Smyth and Dermot Farrell for sharing their cross making skills.
