I did find a couple of pictures of what I was trying to explain. I have done this countless times for some of my tanks as well as doing for others with positive results for many years.
The plastic netting shown is in large rolls at Lowes.(comes in large roles and is cheap) I cut and form large enough to protect the anemone from intrusion from overzealous clowns to afford the anemone to get comfortable once settled where it likes to be...I've done so for as long as it takes before removing.
***I make it to the shape desired, spray with white distilled vinegar, then rinse with RODI fresh before placing over the anemone.
I hope this helps you.
EDIT: Cut off sharp ends of the plastic netting and zip ties before using.
