Found it. Outside someone's renovation-in-motion house. And gave boyfriend a purple bruise on his drunken hip carrying it home in the dark on his bike. See below.
Here is my hunk-a-junk. I sawed off the end planky bit and then cut out the corner and attached it, well see below. (Hanging around in the distance is our Tomte and 'gnome henge'/'brick henge')
So. Held in place with metal bits with screws in.
We visited the Bristol Wood Recycling Centre yesterday and bought another pallet fo £3, and some planks as I had decided on a design for the back rest involving nothing more difficult than slotting them down the back - genius. Undecided as to whether they will be chopped back a bit.
Then spent 3 solid hours sanding off the gnarly edges - upper body stength is lacking so chance of splinter=high.
In the lounge.
Purchased some garden cushions from ikea. To be covered, but the weather is too nice to do any vehicle based outings.
Result - comfort undelivered by previous 'iwasastudentandhadtobuyikeascheapestsofa' sofa.
