Tamil Alphabet Handwriting Practice Workbook for Kids & Adults: Trace Letters & Learn Tamil Script Alphabet | Improve Your Print Handwriting & Practice Print Penmanship

I found these three books on Amazon and wasn't sure which one I'd like, so I got all of them to compare.The red and yellow books seem to be exactly the same, except the yellow one includes a front page that summarizes the alphabet and the paper seems to be thicker. The red and yellow has a page for each letter to be traced.The blue book starts with two lines of tracing, and then blank lines on two pages to write it yourself. There are also drawings of words that have that letter's sound -- which could be helpful for people who already know Tamil language. However, I'm totally new to the language and don't know how to pronounce any of those objects, so those images were not so helpful to me; but I imagine it would be useful for kids who have Tamil parents helping guide them. Also the drawings can be used like a coloring book for kids if they like to color.All three of these seem to be printed on demand from the same publisher
