phew! I agree with a lot of replies here- how would you transport it? support system? budget?
The main thing that concerns me is there are soooo many letters to it. Maybe suggest doing initials? If it were me, I think I would pass on this request and suggest something different. I think it would be too much of a headache and way to stressful!
But I do like the ideas on here of propping up the letters a couple inches up?
Pretty hard request I must say!
