I have some of the same colours, though I think my light blue and purple are probably different, and I'll be using ordinary DMC for the black.
As for the stats: the fabric is antique white 32ct Jobelan, the threads are Madeira no.4024 pale gold, DMC 310 (black), and Carrie's Creation silk in the colours Sunflower, Citrus, Olde Salem Red, Lavender, Blueberry, Sapphire, Rainforest and Gold Glow. You will see from the picture that the shades are not quite "solid", and I hope that that will give a sort of watercolour effect.
The eagle-eyed (eagle-brained?) among you will realise that there is one colour too many -- this is because I thought Sunflower was too bright for the border bits which I would like to look like gold leaf, but Gold Glow was too browny gold for what I wanted in the individual motifs. So whenever there is yellow in the motifs, I'll use Sunflower, and for the borders it'll be Gold Glow with one strand of pale gold blending filament.
Oh, I've made a few changes to the chart, I found the last square too dark so lightened it up a little, changed black to dark blue somewhere and yellow to orange. You'll see
