Decoupage models and paper (Tilehurst RG30)

Hi all, I am doing arts and crafts with ladies with learning difficulties and mental health issues. I am looking for anything to do with decoupage as this will be an easy and therapeutic craft for the ladies to do. We all gather on a Wednesday for 3 hours to enjoy crafting, chatting and just getting together. If anybody has decoupage or any other type of arts snd crafts no longer used or needed, I will give them another well loved second chance of life. Thank you all if you can help the ladies.
