Figure 6. Double-Treble Crochet
Double-treble crochet. ([Figure 6.]) Having a stitch on the needle, take up the thread twice, or put it twice over the needle, insert hook in work, take up thread and draw through, making four stitches to be worked off; (take up thread and draw through two) three times. The abbreviation of double-treble crochet is d t c.
Figure 7. Triple-Treble Crochet
Triple-treble crochet. ([Figure 7.]) Take up thread three times, insert hook in work, take up thread and draw through, making five stitches on needle; work these off two at a time, as in double treble. The abbreviation is t t c.
One sometimes has occasion to use other extra-long stitches, such as quadruple crochet (over four times before insertion of hook in work), quintuple crochet (over five times), and so on, which are worked off two at a time, exactly as in treble or double treble. In turning, one chain-stitch corresponds to a double, two chain-stitches to a half or short treble, three chain to a treble, four to a double treble, five to a triple treble, and so on, adding one chain for each extra "draw."
Parentheses ( ) and asterisks or stars * * are used to prevent the necessity of repetition and save space. They indicate repeats of like directions. Thus: (Chain 3, miss 3, 1 treble in next) three times is equivalent to chain 3, miss 3, 1 treble in next, chain 3, miss 3, 1 treble in next, chain 3, miss 3, 1 treble in next; or to * chain 3, miss 3, 1 treble in next, repeat from * twice.
