Phew, finally done. Actually, given that I was making the whole thing up as I went and had just learned the stitch technique, it went pretty quick. I nearly didn't have enough increases to make the tree skirt lay correctly, but it ended up working okay. The flow of stitches is interesting and works really well with multicolored yarn. I'd been thinking of using it to make items from handspun, but the stacked increases put a lot of strain on the stitches at the base of the stack so I'd be very hesitant to use it with light-weight handspun and that is mostly what I have.
