To Silver Thistle: Flower Power is a separate chart. It's by Crossed Wing Collection and you can pick one up at almost any ONS. The charts on the yahoo group are over one adaptions of the hummingbirds on the Flower Power chart. The pdf contains all of the xml files.
To Cathy: Thread parking doesn't have to be confusing, once someone explains it! Becca has published a very detailed explanation (with pictures!) on the HAED board. Here's a link to her post. This is posted in the forum devoted specifically to parking, so you'll probably find tons of other valuable information there. My WIP looks messy because I start and end my threads by doing a waste knot to the right of my stitching -- only without the knot, I just leave a little tail. So those little tails are under my parked threads, which makes it appear that more threads are parked than actually are.
This is how I do my parking: I work in 10 wide by 50 long columns. I usually start with the first symbol and work that thread until it runs out or I get to the bottom of the 50 rows. I'll then either park the thread in the first instance of the next 10 x 10 block below, or if there isn't one there I'll look to the right and park the thread in the next instance of the symbol in the next 10 x 50 column. I hope that makes sense, I'm not so good at explaining things if I can't use my hands to talk!
