There used to be a small garden shop that had a guy working for them that spent his time doing really creative stuff. I wish I remembered exactly what he did with some of the chairs. (Wonder if I bought my chairs there when they were closing?) Seems like he'd use peat moss along the seat and then plant really pretty annuals in colorful combinations. He also did some really cool mosaic stuff. I bought an incomplete bird bath b/c I thought one day I'd at least re-use the tiles. Sigh. Still haven't done it yet. But it's the light green upside down doodah in the picture above that shows my 'spare parts'.
Hope you get that chair!
