Model Rocket Recovery Wadding

I have used Estes Rocket Recovery Wadding for years and it has never failed me on protecting my parachutes and streamers. If you want a good tight fit then take 3 or 4 sheets of the wadding and lay them across the body tube. Take your finger and poke the sheets down until they clear the top rim. Then take a deep breathe while placing your mouth over the body tube like a blowgun blow hard until the wadding pops into place for a tight seal. Then you can put your recovery device in.
