Gather your supplies
• Plain aluminium sheet 900 x 900 x 0.5mm
• Link chain, length to suit
You’ll also need
Gloves; metal ruler; pencil; flat board; utility knife; nail punch; hammer; fine-grit sandpaper; clamps; rag; drill and bits; rivet gun; rivets; long-nose pliers; cup hooks (3)
Step 1 Decide on shade’s diameter and height. Wearing gloves, mark dimensions as a rectangle on aluminium sheet (add 2cm to diameter for overlap). Working on flat board, use knife along ruler to score and cut sheet on marked lines.
Step 2 On 1 face of sheet, use a pencil and ruler to lightly mark up a geometric design, or sketch organic shapes.
STEP 3 With sheet on flat board, use nail punch and a hammer to punch holes along marked lines, 10mm apart.
STEP 4 Use sandpaper to blunt cut edges of sheet.
Step 5 Bend sheet into a drum shape, overlapping ends by 2cm. Use clamps to hold drum together at join. Put a rag between clamp and metal to avoid scratching.
Step 6 Predrill evenly spaced hole through overlap, about 4–5cm apart.
Step 7 Use rivet gun and rivets to join drum at overlap, through predrilled holes.
Step 8 Drill 3 hanging holes, evenly spaced around diameter of drum, about 5mm from top.
Step 9 Measure desired hanging height of shade (add a bit of extra length for chain adjustment) and use cutter on pliers to cut 3 lengths of chain to suit. Snip and open 1 end link of each length of chain. Hook chains to shade. Pinch opened links closed with pliers to secure.
Step 10 Fit cup hooks to rafter, evenly spaced around light fixing. To hang shade, hook chains on cup hooks. Adjust until level, then trim extra chain
