It was super easy to use. I just copied and pasted all of my blog posts into Word, formatted as I saw fit, turned into a pdf (they tell you how if you don't have Adobe on your computer) and then you just upload it. For a 285 page hard back book it only cost me $60ish with a coupon code they sent.
I ordered Emmy's book first, but was so impressed with the quality that I went ahead and ordered one for Holden. He will just get another one someday :).
The interior quality of the book reminds me of a text book. The pages are somewhat glossy and have a good page feel. I did notice that the images are a little dark printed, but that could because the majority of them are from my phone.
As I mentioned, Lulu isn't just for people who have had a blog. You could easily publish anything you can put into Word - like photos and a journal from a trip, etc. I would say that this is better served for when you have something to say vs a photo book by itself, those are definitely higher quality paper. This isn't a paid ad. Just thought I would let you all know what worked for me.
I know my kids will love looking back on these as they get older! And, truth be told, I have loved looking at them too!
