These nets can be cut into square or rectangular pieces that can be used in the sandtray for themes of trapping and containing.
Let me show you what they look like when you cut them apart and how clients might use them.
I filled it with Malt-O-Meal as I was at home and not at the office so I didn't have any sand available.
You can see that from the two net bags I was able to cut four small, square pieces of netting. You could also just cut each bag in half and you would have two larger rectangular sized nets.
It might be used to trap someone or something such as a bully or a villain so that they feel protected, safe and in control.
Sometimes clients might use netting to contain themselves from being impulsive or from engaging in self-destructive behaviors.
