Okay - I was doing great until I got to the part about 'radius' corner dimension. I have a Marquis Quest Spa - circa 2005 model. It measures 77" x 84" and has curved corners.
I've tried the two rulers, a ruler and a straight edge, a carpenter's t-square and the tracing and measuring methods - I came up with a different radius every time! (everything from 12" - 15.5") I understand the importance of getting the measurement correct - and I even called one cover manufacturor for help - hoping they had a 'template' for my spa... no such luck.
Does anyone else have a Marquis Quest? Or a 'simple' solution for getting the curved corners right? Any Marquis dealers care to chime in with who they use for covers?
Thanks for your help in advance.
