Growing up in a household with a non-practicing Catholic mother and a non-practicing Muslim father was fine until major Christian holidays rolled around. My mom was often into a tradition (a Christmas tree, for example) that my dad wasn’t having.
Except Easter eggs. There were never fights about Easter eggs. My mom, who is from Lithuania, would make traditional Lithuanian Easter eggs called Margučiai. She’d dye the eggs a gorgeous reddish brown by boiling them with onion skins. Then she’d sit for hours, using a razor blade to scratch Fair Isle-esque designs into the eggs.
They were really cool looking. I don’t have a picture of the ones she did, but I found this picture – same idea and technique.
