I didn't take pictures along the way, but you can see how I put these sisters together from two similar makeovers: Antique Hair Brush Transformation and Vintage Hair Brush Makeover.
I added some rhinestones and tiny feathers to her very fashionable hat, and a decorative bead to her fancy lace scarf.
Sister's hat was decorated with a pair of vintage earrings. Her necklace is a small piece of a rhinestone bracelet with a little brass flower for the pendant.
I added some lace and beads around the edges, then attached a rhinestone pin and earring to the top of each handle with E6000 glue.
Hanging around with pieces of broken rosary and chain.
The back of one brush still looks good with its pretty patina, the other one...not so good.
As long as the scale/size looks good, you could fill these with just about anything. I've been searching for the perfect picture of my grandmother so she can be the star of my next brush makeover.
