This is my first attempt at Tunisian crochet and at Tunisian entrelac, I find it really easy and think it's quite similar in look and feel to the knitted entrelac...

What I did :

1. chain 7
2. draw a loop through the back loop of every chain, all loops drawn stay on the hook,
3. working from left to right, yarn over, draw through next loop on hook, then for every remaining loop, yarn over, draw through next 2 loops on hook, you obtain two stitches each time : one vertical, one horizontal,
4. working from right to left, for every stitch, draw a loop inserting the hook in the center of the vertical stitch from the previous row,
5. working from left to right, yarn over, draw through next loop on hook, then for every remaining loop, yarn over, draw through next 2 loops on hook,
6. etc... up to 6 rows. Single crochet across the last row, from right to left, as for a normal crochet project, inserting the hook in the center of the vertical stitch from the previous row,
7. turn your work so as to work on the left side of it, draw a loop from every stitch, keep all loops drawn on the hook
8. etc...

Crocheting the 7th row in single crochet avoids ending up with a right-side-wrong-side pattern, like inMary M's tutorial, gives a result more akeen to knitted entrelac... I think.

The result, right and wrong :

I'm liking it! Loads of fun!
