Colors used on the model are:
NN 183 "Jewels of the Nile" for the border -- straight stitches and Smyrna crosses in the corners.
NN 136 "Navajo Turquoise" for the water -- alternating half stitches.
NN 189 "Kismet" for the goldfish (top and bottom fish)-- cross stitch, completing each stitch as you go in horizontal rows.
NN 172 "Silver Fox" and 1 strand Kreinek blending filament 032 for angelfish (middle fish) -- cross stitch, completing each stitch as you go in vertical rows.

Use 2 strands of floss throughout. Do not "fold" floss, but use 2 separate strands so that the color variegation will match.
