Here is a picture of a pillow case I did with Front Post Double Crochet - (it's put over a colored pillow, that's why you can see blue and white through it lol, I gotta get a plain pillow)
Here's another nice way to create a raised texture on crocheted fabric. It's usually done with double crochet but it can also be done with taller stitches. There are two ways to make this stitch:around the front or around the back of the post (the section below the V of a double or taller stitch). Going around the front creates a raised stitch on the side of the work that is facing you (the front);going around the back creates the raised stitch on the side of the work that is facing away from you (the back). If you're working back and forth in rows and you want to have all your raised stitches on the same side of your fabric, you'll need to know how to do both. When you're working around the post, you aren't really making your stich any differently - you just aren't making it into the top of the next stitch, as you usually do. Instead, you are making it around the body of the stitch, which , on a tall stitch, is long and thin, like a stich - or a post. To try it out, begin with a row of double crochet stitches, made in the usual way.
TO WORK AROUND THE FRONT OF THE POST
Twirl your hook around the working yarn as usual, then stick your hook into the space to the right of the double crochet in the row below instead of into it's V. Then return to the front through the space to the left of that stitch. You've kind of woven your hook around the back of the double crochet stitch, and the post is in front of your hook. Grab the strand of working yarn and pull it all the way through with your hook, guiding the yarn behind the post of the double crochet. Complete your current stitch the regular way (yarn over, pull a strand through 2 loops on hook, yarn over, pull strand through last 2 loops on hook. This is called a front post double crochet (FPdc)
