When my twins were 4 and they showed interest in my sewing, I helped them make place mats. I took a place mat size piece of fabric and put basting spray on it. Then I laid a piece of batting on top of it. I then put basting spray on the batting, making it slightly sticky. I then dumped my scrap bin on the floor and gave them each a pair of kids scissors. They went through the fabric and cut up pieces of the fabrics they liked. They laid those pieces on top of the sticky batting until it was completely covered. I then took it to my machine and FMQ'd the placemat. There were raw edges everywhere, so I did a lot of FMQ. I then put a binding on it and they use it as their placemat!
