I made this farm set for my daughter for christmas, she will be 20months old.
It's all made of felt, the barn is a pocket which all the animals fit in for safe keeping, the roof of the barn is sewn down. The vegetable patch is 2 pockets so she can plant her veggies. The animals are the same on both sides so it doesn't matter which way they face.
It's around 3 foot x 2 foot
