Feb 1st is the feast of St Brigid.  Here’s a little history and tradition about her:

Brigid of Kildare (c. 451–525) was a nun and abbess who founded several monasteries in Ireland. Brigid is the patron saint of babies, midwives, children whose parents aren’t married, scholars, poets, travelers (especially those who travel by water), and farmers (especially dairy farmers).

Brigid is said to walk the earth on Imbolc eve. (Jan 31).  Before going to bed, each member of the household may leave a piece of clothing or strip of cloth outside for Brigid to bless. Tonight is St Brigid’s eve so don’t forget to leave a cloth or scarf outside to be blessed by the saint as she passes. Known as a ‘Bratog Bride’ in Irish folklore, this special garment can then be used as a cure for headaches or sore throats.

Another tradition was to make a St Brigid’s Cross. See above.

Brigid’s cross is usually made from rushes or, less often, straw.  They are then placed in doorways or above windows.  It is traditionally believed that the cross protects the home from evil, fire and hunger.
