If you do still fancy giving it ago or trying something similar, I used bookbinding glue to create the pads. I stacked all the pages and weighed them down with heavy books. This helps to keep them aligned, as well as preventing too much paper warping when the glue’s applied. I used 3 coats, allowing each one to dry in-between. Once finished you can easily peal a sheet off when it’s written on. It’s a bit like a ‘post it note’. I also bought some magnetic strips with adhesive backing. I attached these to the shopping lists so they could sit happily on a fridge.
