Open the handbag and peel back the layer of leather that's glued inside the bottom to expose the brass feet fasteners.
Use a screwdriver to tighten the fasteners into the brass feet so they're not loose.
Apply craft adhesive to the underside of the leather piece. Lay it in the bottom of the handbag and smooth it out while pressing it down. Allow the adhesive to dry for five to six hours to ensure the leather is securely attached.
Wrap plastic wrap around the handbag to cover the leather. Leave only the brass feet exposed.
Place 1 teaspoon cream of tartar and 1/2 teaspoon of lemon juice in a small bowl. Stir the two ingredients together to make a thick paste.
Apply the paste to the brass feet with a dry cloth to coat them. Allow the paste to sit on the surface for 30 minutes.
Buff the lemon juice paste off the brass feet to remove tarnish. Wipe the brass with car wax to add shine. Rub the feet to remove excess wax then remove the plastic wrap from the purse.
