What unique materials and tools does Gabrielle Nistico recommend for voiceover soundproofing?

Gabrielle focuses on cheap, DIY acoustic treatment rather than “NASA-level” soundproofing. Some of her go‑to materials:

• Old pillows, couch cushions, comforters, quilts
• Mattress toppers and foam mattress pads
• Moving blankets and thick household blankets
• Carpet padding or remnants from a carpet shop (covered with fabric if you want it to look nicer)

For structure/installation she suggests:

• A small closet or tight space (less to treat)
• Simple PVC pipe or 2x4 frames for a portable booth
• Velcro, nails/tacks, or construction adhesive (like Liquid Nails) to hang materials

What kind of space are you trying to treat right now—closet, corner of a room, or something else?
