Light winter hat insert

For kids we bought plenty of such winter hats with a fixed light in it. These hats are great during winter time when it's dark outside. As always kids lost lights from some of these hats and where wearing it just with a hole. So I thought why not to create some 3dimensional inserts which would look great instead of these lights. So here you go, 3 first variations.If you are interested in some different object on these hats, write in comments.
