When sewing, care should be taken in joining threads. The manner in which it is done depends upon the stitch in use. In hemming, leave a half-inch of the old and a half-inch of the new thread, tuck both under the hem and continue hemming over the threads. The same plan is followed in overhand-ing. In the blanket stitch, feather stitch, herringbone, chain and buttonhole stitch the new thread must come out through the last stitch. Thoughtful attention should be given to the fastening of threads, as careful, painstaking work may soon be rendered useless by the loosening of the thread from the end. After fastening securely clip off all threads that the work may be not only strong, but neat. The usual fastening consists of several backstitches taken in the same place.
