In the Harry Potter universe, Harry receives a Nimbus 2000 racing broom from Professor McGonagall when he joins the Gryffindor Quidditch team. This is how I made mine for a Harry Potter Halloween party.

Step 1: Always reference your work
First step is to get reference pictures of the broom so you know what to aim for. I used this replica from Cinereplicas as the basis for my build. I imported the side view into a drawing programme and scaled it to the right size for my height. This allows me to work out the ratio of broom to stick and the right diameters. Close up photos also allow me to see what various parts are made of and how things go together. Notice how the back half is more curved like a tree branch and the front end has a sharper curve like it had been shaped into a broomstick.
Step 2: Material girl
1.5m length of 2x6" wood, I used pine
~ 1.0m of 10mm diameter nylon rod
~ 150 strands of willow, bear grass, dry reeds
Strip of 12x2mm aluminium
A piece of 24mm aluminium bracket
A 4" nail
Dense foam (like Plastazote) or cardboard
Various sized screws
Mahogany wood stain
Maroon / Medium brown spray paint
Gold spray paint
Router with radius bit (optional)
Heat gun (a gas kitchen hob is possible but not recommended)
Hot glue gun
Personal Protection Equipment
Step 3: Pattern makes perfect
Scaled up, I drew the stick onto cardboard, cut it out and rode around on it to check for scale. I traced around it onto a piece of 2x6" pine that was laying out in the garden and cut out the rough shape with my jigsaw. I extended the stick into the bristles section for support later. The 2x6" is a good starting point as the 45mm thickness works out nicely without much shaping for a broom 45mm in diameter.
