Your ebooks are helping me with creativity. I am not an artist, and it is hard for me to create something. I do not have a lot of inspiration. I looked at a lot of resources for zentangle on the web, and when I found you, I was really surprised to see how your tiles were beautifull. Than, I wanted to do the same thing as you. :-). When I saw your ebooks, I have decided to try them. I did not know anything about shading, and I wanted to learn. I think you are almost the best with shading!!
There are thousands of zentangles on the web, it is fun to look at them, but when I look at them, I do not create. I begin to create when I open your books. They are well done, easy to follow, and make me realize that I can do something beautiful me either. Your books help me to create without stress, slowly, at my rhythm. When I open your books, and take paper and pen, I instantly be in harmony with my mind, and it makes me happy. It is like a gift.

Just to let you know (in case it doesn't show up anywhere electronically)  your inspiration has travelled all the way to The Blue Mountains in Australia which is where I live. I enjoy greatly your ebooks,  in fact it was the first ebook I have ever purchased. The emails are also a treat. Look forward to my videos and future surprises.  Many thanks, Amanda

I have been an artist all my life, but after using your two main books on shading, it is becoming second nature to me now. And when I am doing more representational art, the shading is almost effortless, whereas before it was a pain.
Thank you so much for my new skills. I have been telling folks that I have learned more by reading the first 15 pages of your shading with color booklet than I did in my entire four years of Art in collage.

"Eni Oken Czt books are THE BOMB> i did a successful jewel on the first try w/ her instructions."

I would definitely suggest starting with Eni's book 3D Tangle: Shading Fearlessly. And if you're interested in using gray markers for shading, buy her new Shading with Gray Markers. All of her books are excellent!

Shading Fearlessly will teach you a lot, even if you are already experienced.

Your e-book is really stunning, I like the way your e-books are all devoloped with great care and great lay-out! Easy to follow by tons of pictures and just enough text! 

Shading Fearlessly is fantastic, even when I am "lazy" about my shading, it still looks better than my shading before I bought the book!

...honestly have you gotten Eni's book? Shading fearless. She takes you through the steps so easy. Really worth every pennie. Once you do the trial samples you will be amazed at your progress. I promise...

... thank you for your awesome tutorials and e-books ... my art work is changing... 

Shading in this way is so much fun. Thanks to Eni Oken for her great ebook about shading.

Eni made me addicted to shading... she's a great and inspiring teacher!

I have purchased several of your pdf books and I am amazed at your talent. Thank you for sharing!

Your books are super! I am working an a second, 9x12 project from Fearless. Thank you so much - my house may never be clean again!!! D.R. introduced me to this art and I am loving it!

You are an amazing teacher! We've never met yet you have taught me so much!

[Fearless Shading]... isn't that a great e-book? I read it three times in the first two days that I had it -- and refer to it often.

I have 4 of Eni's books and they are amazing. Well worth the money spent. When it comes to getting your zentangles to leap off the page in 3D animation, you could have no better teacher. Whether you are a beginner or skilled artist, Eni has the ability to tickle amazing effects out of your pencils and markers. Thank you, Eni.

I will never be able to make a tile again without shading!!! ...so grateful for what [Eni] is doing for us tanglers!

...my first attempt to shading after reading Eni Oken's book Shading Fearlessly. Eni- you're awesome! Thank you for sharing your talent. I'm still gonna tweak it more. I need one of those tiny erasers! Ha! Love your stuff and your blog.

...Thank you for your ebooks. The first one I downloaded from you was the gem book. I’ve tried learning from other sites, but your book finally taught me the right way to do it and now I love the way mine look. Thank you!!

I've been super happy and very impressed with the care you take on making your ebooks. They are great to have on a tablet to glance at while drawing- I keep mine on a cloud drive and find myself even using my phone to read over them.

I'm purchasing Narwal at present. I just love your books and I'm getting so many compliments on my new found shading skills. You rock Eni!

Eni Oken has an ebook [on shading] that is fantastic. Check her out. She has taught me so much.

Wonderful...Eni, you have transformed the shading of Zentangle forever with your books and expertise on shading. Thank you for sharing your expertise

Eni Oken's books are incredible. Bought 3 also, but am on my third read of Fearless before I venture farther. My head holds only so much, and the books are crammed with good info.

Eni Oken Thanks, your books are so well done making each step easy to understand...can't wait for the next one.

Eni, Your two print books were delivered yesterday.  I sat and read them without making a move.    They were nicely wrapped and of excellent quality.  And the content was wonderful.  You did an outstanding job explaining everything.

All I can say is WOW!  Thank you for opening new worlds for me with your wonderful instructions and stunning artwork!

I love your printed books from Lulu. They are so nicely printed and the packaging amazes me because they *really* protect the book inside. I'm going to read one now and look forward to your 3D one soon!

Eni, I've loved your work and your tutes since coming to your wirewrapping materials years ago. How wonderful that you're into ZT's now!!

I have bought your shading fearlessly book and last night bought the gemstone book. Both are FANTASTIC. I had success with the first 2 gemstones I attempted! Thank you for your immense creative gifts as a maker and a teacher. You're awesome in every way!!

I enjoy e-books, because there is no hassle coming from Eni's site. This e-book is chocked full of ideas, techniques and a material list. This is one of the best e-books I have purchased. Eni does a great job as a writer.

I am learning so much from the Ebooks you produce. I like the details you put into them and thank you for the challenges in learning new techniques.

If you don't learn from these books, nothing will help you. Even the tiniest detail is explained - nothing left out - nothing to add. Eni's books are the Best !

Eni - I just want to thank you for those e-books. I got my 3rd today - I love them

I think your books are great. I've learned so much from them.

Eni, your creations are always so stunning. I don't know about others, but I do find myself hanging on your every word when you critique my work or others. I always study the tile after your comments. I've learned so much and am grateful for your time and talent that you share.

Your work is really inspiring to me and I have learned so much from your books. I never thought I would be able to do color (other than a colored Micro to draw my tangles) and what you have taught me to do has given me great joy. Thank you!

I love your books and am going to make sure every time I post something I give you credit. You have helped me expand my shading sooooo much {heart emoticon}

Yes! Yes! Yes! Get the book! Your zentangling will enter a new dimension of discovery. Eni's books are so well written with clear illustrations and steps that make even the most inexperienced zentangler create awesome art. It is as if she unlocks the artist in you. Worth every $!

You should try to save up for Eni Oken's ebook, Shading Fearlessly. It is specifically about shading zentangles and is fantastic!

I highly recommend Eni Oken's books. They are life changing. She is a master of shading and makes it look seamless with her step by step instructions. I have several of these priceless ebooks.

Love your e-books! Eni 🤗 Quickly went through the last two and was still able to find some great techniques and tips. Just amazing.....keep them coming please!
