Underwater 10 in Plastic Canvas All 25 plastic canvas patterns in this book are made from a full sheet of 7 count plastic canvas mesh. On each pattern we have made the grid "easy to count" by leaving a row of holes along the outside edge of the pattern. These were designed for any crafty person who would like to change the patterns up a bit or stitch in your choice of colors. You can stitch using the colors charted or in any color you like using a medium worsted weight yarn. Some patterns include more than one shade of a color and this is used for shading. If you don't want to stitch the design with the shading, simply stitch the entire area using just 1 shade of the charted color. All stitches are done using a Continental Stitch, and to finish, overcast stitch the edges! Dancing Dolphin Plastic Canvas Patterns
