How to improve kids hand writing?

We all have good handwriting in our family. We were trained by our parents before on how to write properly, and neatly. This was also taught continuously in school. Now, I have a 3-year old nephew and we are starting to teach him how to write. He's pretty fast in learning though. Plus his writing was good too. We started training him using connect-the-dots activity book of letters. Then, we are assisting his hand as he connects the dots. Now, he can write alone by himself at that age. Time for kids is really valuable if you want them to learn. Just like my nephew. We alternately teach him stuffs like this, so he is very much eager to learn more and more each day. And it works... He gets better each day!

We have to practice and practice until we improve our hand writing. I don't think there is any other method. When my children were young I used to practice them in double line and four line books. But still they have horrible hand writing!That looks like a doctor's prescription. I have to take them to a medical store to get them read. These days I don't see their hand writing atall. I get only mails from them. Who needs a hand writing these days?
