Here are two easy ideas I have done in the past to display the things our family are grateful for ...
1. Thankful Tree
Family members write what they are grateful for on the leaves and display them on the tree
2. Thankful Turkey
Have your child write what they are grateful for on feathers and attach them to a turkey
3. Thankful Tree using actual branches
This isn't one I made but I don't have a picture of the one I made before :)
