I was sceptical having read some of the reviews however there were quite a few that seemed positive so I chanced it. Very glad I did!... Coversandall have remained in contact throughout and although I haven't yet received one small cover I have received, withing 2 weeks, 4 very well made sails to my exact measurement which fit superbly and enhance the pergola to which they are attached as well as providing the shade required. I would definitely recommend this company and would gladly use again myself when required.
