Last time I looked in the local fabric store, they were selling heavy felt for the about the same price as burlap. Seems like a better choice both for appearance and for capturing fiberglass shed.
It is best if the fabric covering is fire resistant. Some burlap smells like it has absorbed some mineral oil, and that's running the exact opposite direction.
Products like this really work:
We applied a product like this to felt by cutting the felt to size, saturating the felt with the fire retardant liquid and then putting it through a spin cycle in our washer, and capturing the fluid ejected during the spin cycle and recycling it.
