Connie,
Using netting as a deer deterrent is usually considered more effective than repellents. If used as a fence it should be at least 5 to 6 feet high and secure to the ground at the bottom. It can also be placed over a small shrubs. After considerable damage to 3' high yews, I put black netting over them anchoring the netting to the ground. I had no further deer damage. The netting was black plastic and hardly visible. It was a 3/4" mesh. I've seen similar netting in hardware stores, but did find mine on line. Below is a UVM web site addressing various deterrent methods for keeping deer away.

DO NOT tightly wrap individual plants with burlap as this can collect ice, trap moisture and make plants more susceptible to infection by disease-causing organisms.
Construct a barrier of burlap or similar material on the south, southwest, and windward sides of evergreens. If a plant has exhibited injury on all sides, surround it with a barrier, but leave the top open to allow for some air and light penetration. Surround your young plant with a few wooden stakes, allowing a few inches of space between the stakes and the plant. https://extension.umn.edu/planting-and-growing-guides/protecting-trees-and-shrubs-winter#deer-972413

Connie,
The netting itself will not weigh the arborvitae down. You don't mention the height of the shrubs, the distance between them and if they need protection on all sides. If they need protection on all sides, you could wrap the netting around the shrubs like a fence using stakes to support the netting. Start at one end of the hedge continuing all the around both sides of the hedge until you come back where you started.This can be done close to the shrubs even touching them with the netting touching the ground. There would be no need to tack the netting to the ground. Netting installed touching or very close to the shrubs should be at least 5 feet high.
I hope this information is helpful.
