Here's a closer look...
Lemon Peel stitch was worked first. This is a very simple yet effective texture stitch, called 'Lemon Peel' by Jan Eaton in her brilliant book '200 crochet blocks for blankets, throws and afghans'. I would highly recommend this book and it was one of the first crochet books I bought. Just alternate treble stitches (USA dc) and double crochet stitches (USA SC) worked in rows.
The next band on the swatch was simply double crochet (USA SC) and where the yellow dots are on the photo, a front raised treble (FRTR) stitch. A FRTR stitch is made by inserting the crochet hook around the stem of the stitch in the row below, but is actually just a treble stitch (USA dc) but the diffenrence is where the hook is inserted into the fabric of the crochet. I do like the effect it gives .
Finally I did a band of Moss stitch, which is fast and super easy. Moss stitch is made with a dc (USA sc) followed by a chain stitch, in rows. The dc stitch (USA sc) is always done into the chain space in the row below. The beginning of the band on my swatch is a full row of dc (USA sc). I totally love this super simple texture stitch.
The only thing is, this swatch is very blocky and regular. I am going to turn it into a scrumble (watch this space)...!
