I used Blog2Print to make my blog posts into a book. I've made two books and I have been very happy with both. You can pick the outside color, pictures for the front and back, and text for the spine and introduction.
I enjoy flipping through it and reading my posts and seeing the photographs.
I selected the compact method, which didn't always keep the photos and their text on the same page, but did save some pages. Overall it is a high quality product, a keepsake. One I hope some distant relative somewhere down the road will enjoy perusing.
