How to achieve a spiked fence look

You will need :

Plastic corrugated sheet

Ruler

Pencil

Marker

Sharp Knife

Black spray paint

To start with, draw pencil lines down the sheet at every 3 inches, and across at inch intervals.

Using a marker, draw a line from alternate 1 inch lines at a diagonal to each 3 inch line, then draw your next diagonal from the 3 inch line back to the next 1 inch line down, and by extending each line through you should have a number of diamonds 6 inches long by 2 inches wide which you can now cut out.

Next you will need to make vertical cuts 5/8 inch from each side and 1/8 inch wide. This leaves a centre piece ½ inch to insert into your fence post

Spray black and insert into each post on your fence
