Step 1:Necessities etc -
What you'll need...
- cloth hat
- sewing machine / #10 hand sewing needle
- pencil / chalk
- thread
- scissors
- scalpel
- cutting board
- beer...


Step 2:The Process -
The pictures should express most of it really, but here goes -
Find a suitable candidate. White to reflect the sun, canvas to breathe, and CHEAP.
Cut the crown off - to minimise discomfort and maximise ventilation. I cut less off the back to cover the big gap. The front is about 30mm high, and the back is roughly 80mm...
Mark the slots for the chin-strap, and cut out with the scalpel. It's easy to cut more out later, but harder to fix if you remove too much too early... I cut the slots about 4mm wide and 120mm long
Check that it all fits before you finish it...
Bind the edges. With a sewing machine, or by hand, zig-zag or blanket-stitch over the cut edges to keep the fabric from fraying. Reinforce the sliced-through vertical seams by sewing back-and-forth a bit.
Now whack it on ya noggin and get cyclin', safe from the sun.
