Looks like building planters is the job of the moment. I built one from decking planks over the weekend.
No screws in the sight here, all dowelled and glued:
Spare/scrap timber used for the base:
Lined with a car boot liner from Homebase. The liner was £1.99, garden polythene was £20 a roll!
In place, filled with compost and beans planted:
The legs are screwed to save time and faff.
Very pleased with the outcome, particular the sides as it's the first big thing I've built with my new Jessem dowelling jig.
