The curtain looks like this when it hangs at the window.
Working the Border.
Now look carefully at the border and see how this is done. You have an illustration showing how to make the various stitches used. You first work slanting up-and-down stitches all along the side edges and across the bottom of the curtain, going over 4 threads of canvas.
Commencing from the top of the right side edge of the curtain, count 4 threads from the top edge, and put your needle up through the hole right on the edge; go over 4 threads to the right and 4 threads up, put your needle in and pick up 8 threads; make a slanting stitch back again down to the edge of the canvas, and put your needle into the hole you first brought it out of, pick up 8 threads along the edge, and repeat this up and down all the way round three sides of the curtain.
I think the little picture will best show you how this is done; you will see that two slanting stitches meet at the corner. In picking up the lower threads only take up the single canvas, so that no stitches will be shown at the edge on the other side.
A CORNER SHOWING THE BORDER.
Now to complete the edge, buttonhole stitches are worked around. Directions for making buttonhole stitch are given on [page 6]. One stitch is placed at each point of the slanting stitches, putting your needle down through the fold of the edge of the curtain. How this should look can be seen in the second specimen in the illustration of the stitches. You will notice that three stitches are made into the one hole at the corner.
