This was an inspiration from @minimadthings. I felt in love with the idea of turning cardboard into an adorable craft that can be worn while allowing children to do some pretend play!

Measure the child’s back to have an idea of their size then draw out the wings in a cardboard then you can decorate it however you want depending on the materials you have handy.
Make four small holes to feed ribbons to secure the wings to the child’s wings.
