How to make a simple sentimental gift
Buy a tall and transparent jar or container, with a lid.
Preferably, it should be something that has a very firm lid, to prevent spills. A pretty container that will be useful for future purposes is ideal.
You can use any container, but this gift idea will work best if the container is fairly tall, and a little wide. The next steps will give you an idea of how you'll be using the container to provide a better idea for the size and type.
