I have a 4 year old with big plans and a former carpenter/current engineering student dh who wants to help him fulfill them. We need a book or a magazine or a blog or something with FULL plans for the project (i.e. materials list with dimensions and step by step instructions - dh can make time for the projects but not for making the plans first). And we need the projects to be more work with balsa or thin plywood so ds can actually hammer and get a nail through the wood. Any ideas? I'll cross post in homeschooling also.
