I believe, as do many other people, that Tunisian Crochet is a hybrid or combination of Knitting and Crochet.  Consequentially, elements from both can, theoretically, be worked in Tunisian Crochet.

One of the most popular methods translated from Knitting is Entrelac, which is French for ‘interlacing.’  I have a booklet on Tunisian Crochet Entrelac that uses a method I created and visually resembles Knitting Entrelac more so than traditional methods of making TC Entrelac.

I purposefully re-learned to knit just so I could translate Knitting Feather & Fan into Tunisian Crochet.

I issued a challenge to the members of the Yahoo group: tunisiancrochet to experiment with Knitting instructions and use the exact instructions, but worked in Tunisian Crochet.  
My first experiment turned out to be something I had done years ago: Arrowhead Netting.

Knitting Instructions:
Simple Lace Stitch (Arrowhead Netting in TC)
Multiples of 2
Row 1: K1, (yo, K2tog) across row, end with K1.
Row 2 and all even numbered rows: P
Row 3: K2,  (yo, K2tog) across row.
Repeat these 3 rows to create pattern.
