The plan is to have straws or other simple sticks standing in the jars. It is then possible to attach something decorative to the straw or stick.
We are using tissue paper to support the straw or stick inside the jar.
Simply wrap the tissue paper around the straw.
And stick it into the jar.
The tissue paper contributes to the look of the finished piece. You can play around with different colours and you can also use other things, such as for example newspaper pages or tulle.
