This is an easy, fun, and thoughtful crafted gift to make.

Here are the steps to make it.

1. First, paint or decorate the jar lid in colourful designs for an extra nice touch.
2. Then trace a phot ograph or a drawing with your jar lid.
3. After that, cut out the picture and then glue it to the inside of the jar lid.
4. Cut out a triangle shape from cardboard.
5. Next, paint or colour it in colourful designs (on only one side).
6. Then fold a triangle at the top of it and glue that folded triangle to the back of the lid so that the bottom of the triangle is also the bottom of the photograph.
7. Let it dry completely before using. This is a great gift for somebody you love.
