Three more squares for  Knit-a-square  charity.   Single Rib Crochet  Square   This was a nice surprise as I've done this stitch before in other projects so I picked this stitch up very quickly. I think the first time I came across this stitch it took me a while to get used to and I kept forgetting if I was stitching in the back or in the front. This stitch uses front and back post trebble crochet (UK) or front and back post double crochet (US). I think these stitches are very useful to know, they have appeared in a few patterns I've followed.   The end square I was surprised with as the texture is very thick and soft, it's a nice texture to rub your hand along... Which may sound a little strange but it's an interesting texture. The stitch looks the same on both sides.       Afghan Stitch  Square   This was the first time I have ever tried Tunisian crochet, to be honest I had no idea what it was before I gave this ago. Turns out it's like knitting but with a crochet...
