I think OK for a flower bed, but quite dodgy for veg. After all, the bed is going to be dug over or forked at least once or twice a year, it's easy for a tool to slip, land on the edge of the glass and break it. Broken glass on a plot is a nightmare.
I think Obbelix built one in their garden - but note it was their garden and not an allotment. Don't know where you are growing your veg Pookienoodle (great name BTW!) and if this would make a difference to you?1066
I think Pookie's been put off the idea now, I think she's lost her bottle. :-X ;D ;D ;D ;D ;D
