to hang on doors and has other pagan stuff...
it mentions that these baskets should be delvered on Belataine
and has other activities for other seasonal occasions.

I am reminded of the Ukranian Easter Eggs, Pysanky, which
have been made for many many years. There is a belief that
the making of these eggs with their symbolic designs, brings
on the new spring and helps the seasons continue!
