Your stitches should be close together, touching and neatly formed. You want to watch for uneven stitching. This may happen by either missing the corner hole or by pulling the thread through the hole above it. If this happens, just unthread the needle, gently lift the mistake with the tip of the needle, making sure to get the entire strand of thread, and pull out. It is a good idea to draw a very light line through each row completed on the pattern so that you are able to keep track of where you are.
Small patterns can become confusing and double rows are a common mistake.
Follow these steps throughout the entire pattern. Be sure to count carefully, and use the color marked by the exact symbol given. When you need to change colors or you are at the end of your thread, run the needle through the back of the canvas, under a couple of stitches, pulling the thread through. Snip the end of the thread, leaving a very small tail. Backstitching is the final touch.
