Fedrigoni Calendar Brief - Wall Planner Sample inclusion

I had an idea to create a cut out section on the wall planner to include a sample of paper for each month to be kept as a sample, but I have no time left to implement this idea so I will just explain what I would do.

I would create samples of coloured paper that are the same design as the tabs on the calendar month pages and then make a small incision on the wall planner for the tabs to slip into, which would hold them in place and once the wall planner or month has been used, the samples can be kept and the customer will still have a sample of paper, with company details on them.
