1 Stockpot from Aldi
1 Sleeping Pad (foam mattress for backpackers, I had one lying around, but available from Halfords for £2.00)
Pack of A3 Foamboard
Kid's PVA Glue (Literally. Morrisons call it "Kids PVA Glue" Apostrophes cost extra.)
Side: Cut sleeping pad to height of stockpot and twice the circumference with scissors. Wrap around twice and tie on with string. Cut notch for the precision cooker's clamp.
Base: Cut two disks from sleeping pad, glue together and compress until glue sets.
Top: Cut five disks from Foamboard with a craft knife, three slightly larger than stockpot, two slightly smaller. Cut notches in each for precision cooker clamp. Assemble with the smaller disks underneath, glue together and compress until glue sets.
Tips: Use the original stockpot lid as a frying pan lid. Temporarily remove the foam sleeve to use the stockpot as a stockpot.
