Can anyone recommend a really sturdy Christmas Tree stand, for big (7ft plus) real trees? We have one of the old style ones, a sort of cylinder with three legs coming out at different angles. It does the job, but now I want a Christmas tree skirt/collar, I am finding it's just too wide to find one that will fit. I'm looking at the options on Amazon, but they just look too small to reliably hold up a big tree!
