With the loop of last stitch on the hook, twist the cotton over the hook, place the latter through a stitch, draw the cotton through, then put the cotton over the hook, draw the cotton through two loops, and again through two loops.
1816. Double and Treble Long
With the hook in a loop, twist the cotton twice or three times over the hook, and draw the hook successively through either two or three loops.
1817. Square Crochet
Square crochet is also sometimes used. The squares are either open or close. An open square consists of one L, two Ch, missing two on the line beneath, before making the next stitch. A close square has three successive L's. Thus, any given number of close squares, followed by an open, will have so many times three L's; consequently any foundation for square crochet must have a number that can be divided by three.
1818. To Contract an Edge
This may be done in Dc, or long stitch. Twist the thread round the hook as often as required, insert it in the work, and half do a stitch. Instead of finishing it, twist the thread round again, until the same number of loops are on, and work a stitch entirely; so that, for two stitches, there is only one head.
