A few people have asked how I created the hairbrush so I thought I'd share the process with you.
Take a paintbrush. Any paintbrush. I used a cheap artists brush for this. Trim the bristles so that they're absolutely flat along the top then add a layer of glue. Leave to dry thoroughly. *
Draw your hairbrush shape onto a very thin piece of wood.
Using a craft knife, roughly cut round your hairbrush shape. (Sorry it's fuzzy but you get the idea).
Gently sand/file round the shape until you're happy with it and it resembles a hairbrush. I used a needle file.
You can either paint or wax your brush. I used brush on/buff off wax.
When the glue has thoroughly dried on the bristles, add a layer of glue to the hairbrush form, gently lay it along the top of the bristles making sure everything is in alignment and leave to dry.
Cut the hairbrush from the paintbrush allowing extra to trim. Ensuring that the bristles are well and truly stuck to your hairbrush, trim them to size.
You are now the proud owner of your own hand made mini hairbrush.
