There is a technique called Cro-Tat, which is a technique between Crochet and Tatting: the item it is crocheted, but looks like tatted. For tutorials look beneath the Links.
I don’t have a straight steel crochet hook and so I figured out how to do this in another way.
It is a kind of clothesline crochet: I am crocheting a simple chain that I ‘decorate’ with single crochets.
I once wrote a (German) tutorial on how to make a Mother’s Day card with a Simple Cro-Tat Ornament. It is heavily illustrated ;-)
Anyhow: ‘Luftmasche’ is chain, ‘feste Masche’ is single crochet and ‘Kettmasche’ is slip stitch, the actual row is red, the previously worked rows are in black.
