Margaux Meganck makes beautiful Matryoshka bird sets. I fell in love with these the first time I saw them and I'd love to hold some in my hands and slowly open them one by one to see the next little bird inside. It looks like she painted these so lovingly that they are probably guaranteed to be full of tiny details to discover and examine. She's also a pretty darn great illustrator and an all around wonderful person. You can see more of her birds and latest illustrations on her blog here.
