Report paper and handwriting

Hi Nicholeen I had submitted a question a few weeks ago but it didn't go through. It was about how to write a report. This topic was brought up from another question and I was to ask you later if I needed more clarification on how to write a paper on a book. I have a new question also now on how you taught your children to have good handwriting if that was something yall did I don't know. I was thinking about this area because we have such a tough time with it from my 16 year old to my 7 year old and maybe we should work to improve it. There is this product from groovecaligraphy.com with ink that disappears and you can write in the grooves of preprinted letters and numbers over and over again without using up the paper. I thought this could help but I wanted your input on it. Thank you!
