I think it is easy but need a little time to do a needlebook.
My cartonnage tecnic is not professional, I just wanna show you the steps.
I apologize for my mistakes, I hope you understand what I wrote.
cardboard paper (thicker to the outside covers, thinner to inside covers)
cotton ot patchwork textiles (I used 2 colors)
fluent adhesive
document clips
wadding or felt substance
pins
mother of pearl threadholder rings
Cut the cardboard paper to that size you have choosen. Cut the wadding too, and put it onto the cardboard paper. Put your stitching on them and its backside draw the linen together with tacking. Now you have this:
Cover the cardboard cards with textile and smear the adhesive in a very thin layer.
Altogether 4 pieces of cardboard cut a sheet out in same size, the pieces marked for the inner side may be made of thinner cardboard. I made an inside pocket too.
Now you have 4 pieces. To make sure the the adhesive sets well use document clips.
It's time to glue the front and back of the needlebook together.
The exterior and inner part of its front after gluing documentum I confirm it its views with clips, the adhesive sets certainly so. I also do the same steps with the rear sheets. Of course something needs let it bind the two covers: I cut a stripe from the textile and I make it driving up between the covers sticking. A book will be from it so.
Needlebook inside. You can take into a piece of felt substance for your needles, or sew mother of pearl rings to hold thread. Pocket is useful holding scissors.
