Ukrainian Pysanky maker...beautiful...the egg i got
from her is missed

i tried a few too, but made them the traditional
way (with the egg intact...yoke and white inside
or i guess that is yolk, ) anyway i will insist
on blowing out the innards of any others that i
make as the ones i made exploded in the attic --
phew!! what a stink...

i did get a few chickens from an interewsting breed
that lay (notblue and green colored eggs as auaucaunas do)
but maroon or brick red-brown eggs...Marans from france
