Hi rilan, welcome to kirigami addicts. I started to do kirigami since last summer and got two kids involved. They are 8 and 10 years old and started to cut paper projects since then. They used just a ruler and x-acto knife to do the cuts. They made over 30 projects and exposed them at a local library. It was an article about their work in a local newspaper. To make story short I would suggest to go and buy a wonderful book The Paper Architect: Fold-It-Yourself Buildings and Structures by Marivi Garrido and Ingrid Siliakus. You can use the patterns in a book and copy them to make wonderful creations or go on YouTube and find some ideas there. Good luck!
