A quick easy and cheap fabric softener is white distilled vinegar. Use this in your downy ball instead. Your clothes will come out softer and no they won't smell like vinegar.
For scented softener, simply add some extract or essential oil to the mix until you've reached desired scent. Be sure to shake well before each use as oil and water will separate.
*This softener will not only soften your clothes but it will also guard against static.
