1. Work from you, holding the canvas over the left forefinger.
2. Insert the needle from underneath, at the lower left-hand corner.
3. From the place where the zephyr comes out, count to the right four threads, then forward four * threads; insert the needle, and pointing it towards you take up two threads.
4. From the place where the zephyr comes out, count to the left four threads, then forward four threads, and take up two threads as before.
5. Continue in the same manner, making the stitches to the right, then to the left; the zephyr crossing diagonally (Fig. 89).
6. Notice that the little cross at one side, comes between the crosses on the opposite side, and that the needle comes out on a line with its insertion for the previous stitch.
7. Turn the corner, by taking a stitch at the left, insert the needle at the right, and pointing it towards the left, take up two threads (Fig. 90). Turn the canvas, and holding the next side across the left forefinger, continue as before (Fig. 90).
In catch-stitching on flannel, small knots may be made if they can be concealed. When ending, fasten the thread by running it in and out under the last stitch. The thread can be fastened in beginning and finishing, by leaving an end to be sewed over and over with fine cotton on the wrong side.
The raw edge of a hem on woollen material may be fastened by catch-stitches, to avoid the ridge formed by folding the edge. The edges of a seam in flannel may be fastened in several ways; the seam may be folded to one side, and the edges fastened by a row of catch-stitches; the seam may be opened and each edge fastened separately; or, with the seam opened, a row of catch-stitches may be put in the middle.
