(Sidenote: I don't live in Bath or London. Just travelling through now and then.)
And on to what's needed:
- Fake leather or other sturdy material
- Exacto knife or something similarly sharp
- Some serious industrial strength glue, E-6000 is the crème de la crème of craft glues
- Not pictured, but bobby pins are hugely helpful
Fold the material and measure and mark the needed width and depth. Make sure to leave some room for glueing the sides.
Press the prongs of a stud into the material so it leaves marks. Use the exacto knife to make holes through the marks. (If using an exacto knife, make sure to be careful to not make the holes too large.) This will help fitting the prongs of the stud through neatly.
Place studs wherever you want them. Be creative and make a studded bow/flower/whatever and glue on. If placing studs vertically or horizontally, use the ruler and pen to space evenly. With the pliers, close the prongs.
Glue the sides, fold and use some bobby pins to add pressure until the glue dries.
