I found an excellent tutorial on Pinterest for Tunisian crochet. I think it is a little tricky at parts, but have learned to loosen the tension which helps a lot! Here is a 2 inch (11 chains) practice square using Loops & Threads Cotton Club yarn in Vintage. I love these colors and I think the different colors really show the stitches well! Now I am on to 21 chains. Find the tutorial here: http://crochetingthedayaway.blogspot.com/2011/10/tunisian-crochet-how-to-basic-tunisian.html
I am still talking to myself apparently, but eh, that's alright!
