Step by Step (Kind of) Edit
To start the challenge, you download the alpha version. After you've done that. You need to start to build a house. It doesn't matter what it looks like. It doesn't matter if you make mistakes. Because I did! Really, It doesn't even have to be a house! Just build what your imagination tells you to. It's just a house is recommended.
If you draw something other than a house, it needs to be child appropriate. Thank you.
Don't want to build a house but have no ideas? Edit
Go to this website But please note: You are not going to be able to build some of the ideas on this website because some require stuff other than cobblestone. But most you can build.
