How do you change the first sheet of a Post-it® Note to be a thicker material?

Sorry it is not possible to change the first sheet of the Post-it® to be a different material. All 25 or 50 sheets of your pad will be the same genuine 3M Post-it® Note paper. What may be possible would be to have a Notepad with a different paper stock as the first sheet. This would be treated as a custom project and you would need to contact our Support Team to assist in pricing and placing this order. Please make sure to provide as much information as possible for us to be able to get back to you quickly with a detailed response.
