Tunisian crochet is known by several names. You will find it referred to as afghan crochet and tricot crochet. It differs from standard crochet as it is made by using a long crochet hook with a stopper at one end that looks like the head of a knitting needle. This form of crochet was popular early in the twentieth century.

It is interesting to see you posting about Tunisian crochet and freeform and stuff – I have done both of those too, and I have a friend who writes Tunisian crochet patterns too! (we are both on http://groups.yahoo.com/group/Australiacrochet/ as well as a few other crochet related lists – yes the art of crochet is alive and well … or at least talking about it is 😉
Actually it is interesting reading your whole blog – I really should read it (and a few others) more often than I do … I probably should write in mine more often than I do too! … but I never seem to have enough time … maybe that should be my “wisdom of the ages” thing – there is never enough time – LOL
(actually I will write something a bit longer/better than that and send it in … if I don’t run out of time) … that is after I go make myself some vegemite on toast! (yes – I feel like some after reading that post about fibre allergies – the one that ended with the bit about going to eat vegemite on toast!)
