I took my pictures and the poem which I had set up on my computer to the copy shop which then printed everything on my fabric. I have since then printed directly onto T-shirt iron-on paper myself, which works the same way. The finish is stiff and shiny, like plastic, which is fine for the purpose - though it does have to be ironed with care.
The cover is softer than the pages, with a thick layer between the visible surfaces. I decided to go for a clean look, so sewed the layers right sides together, then turned them. I allowed for additional thickness with more fabric for the spine; until it is needed, it's laced to hold it together.
The pages are backed (both sides) with a very stiff iron-on facing. I sewed them right sides together as well, leaving the side for the holes open for turning. I then sewed a sturdy twill tape to that edge to finish it and give stability before punching holes and eyelets into it. I sewed matching cords to the cover spine, which go through the holes and are tied together at the top. I also used my sewing machine's embroidery stitches to embellish and stabilize the page edges.
I like the loose-leaf principle for a book like this that is used as a scrapbook. It gives me the option of adding pages in time, as needed. I am currently working on a family scrapbook along the same line (which will be a gift, so I can't show it until after the occasion).
