Blanket-stitching is used to secure and ornament the edges of woollen material.
1. Work from left to right, holding the edge of the flannel towards you.
2. Beginning at the corner, insert the needle one-fourth of an inch from each edge, and take two running stitches to the edge, leaving an end of the thread to be cut off afterwards. This brings the thread in position for working.
3. Holding the thread under the left thumb, put the needle in where it was first inserted.
4. Draw the needle through and over the thread (Fig. 94).
5. Holding the thread down with the thumb, insert the needle one-fourth of an inch to the right, and parallel with the previous stitch.
6. Draw the needle through, and over the thread, being careful that the thread lies loosely on the edge of the flannel.

7. Continue in this manner.
8. To fasten the thread, turn to the wrong side, take a running stitch under the last blanket-stitch. Draw the thread through, and cut it off.

9. To join the thread, put the needle in under the last stitch, as in beginning the work, and draw it out over the thread that lies along the edge.
If the thread is not fastened and joined carefully, the symmetry of the stitches will be broken. The order of the stitches may be varied by taking them at different depths, and leaving spaces between, as in Fig. 95.
A pretty border can be made with this stitch (Fig. 96), by making the first row the desired width from the edge, and taking the stitches for the second row through those of the first row, and so on.
