I would be really careful using vinegar and baking soda on that antique fabric. Call a LQS and see if they have the Restore or something similar. There are so many opinions, all good, but the vinegar and baking soda are caustic. They are chemical reaction when used together and may damage that fabric.
How wonderful that you are willing to work so hard to have something special of your family. I am the same, new doesn't impress me, something of my family....THAT's the pull on my heart.
Good luck,
hugs,
