If you are an academic mother, you have the task of making your kids' Raisin strings. These can be purchased from BESS (the Students' Association shop, at the front of the building) or if you're feeling creative, you could make your own! Just remember:
3rd Year Mothers: use only THREE strings, red, blue and yellow.
4th Year Mothers: use all FOUR strings.
Twist the strings together rather than weaving them - Raisin strings should be decorated with fun items that represent your children, and you should be rewarded with a gift (customarily a bottle of wine, which has come to replace the traditional pound of raisins!)
