Stiched up

So while I am ironing out details I need to sort out how the spine will be attached or worked into the main fabric. I have looked at different seams as i think this is the neatest way of building the spines in and also the most cost effective. At this point I am not choosing one but making my self aware of them at this current time.

I have also considered at this time if i go ahead with my knitted material I could thread the spine through but this will come with issues if the spines does not fit or needs to be replaced. I also am aware a seam is stronger.
