I found this idea here Fabric Covered Books (creativitE by Erin Bassett). and I think that is a good idea if you want make your favorite notebook look special and it is so easy.
This is what you need: A good quality glue, a old plastic credit card, fabrics, scissors and a notebook to cover.
Apply the glue on the surface of the notebook, and using the plastic card spread the glue evenly.
Attach the fabric and make sure that the fabric is flat without any air bubbles, you can use a rolling pin for that.
Here you can see the cuts that you need to make in the fabric.
Here you can see the folds that you need to make.
Have a good weekend everybody !!
