So, having measured up really carefully, and put it up as per the instructions, turns out I’d only gone and put it in the wrong place after all
So, second time round, after being super careful, checking and double checking, I was 99.9% certain it was right this time (I’d only put the ground stakes in at this point).
Asked hubby to check it for me, my goodness I’ve only somehow got the width wrong - 1.3M instead of 1.5 - how on earth have I done that with all that checking and double checking?
Thankfully it’s only 3 metal ground stakes I need to move, but I very nearly finished it with the uprights and everything. Thank goodness OH saw the error before I did
