I think it will be beautiful. To check you could set up a couple of mirrors to get the effect of the kaleidoscope design. It does look like a fairly long repeat, so you will need quite a bit of the fabric for 6 (or 8) repeats.
I meant to add - if it's a vintage fabric, and if it has been washed (or needs to be) you might have a problem. It's recommended that the fabric for a OBW not be pre-washed. That makes it easier to line up the design elements in the layers.
