The FFXIV Blanket.

 First square is done:

 

 

 (This is actually the third square. I am redoing the first two, due to using a different stitch.)

Hopefully I will get a photo of the pattern to insert here:

Here is the stitch I am using. I don't want to say I invented the stitch, as crochet has been around for a few hundred years now and I imagine someone else at some point has done this. But I have not seen it on the internet or in my books, so I am just going to call it:

Reversible Tapestry Stitch.

Use a single crochet foundation stitch instead of a regular chain. This counts at the first row. The second row should be comprised of regular half double crochet. The first and last stitch of every following row will be a regular half double crochet.

 

To make reversible tapestry stitch: yarn over, insert hook into the middle of the V from the stitch underneath it (not under the loops as with most crochet stitches), yarn over, pull through the fabric, yarn over, pull through all 3 loops on hook.

It is really simple, you are just doing a half double crochet inserted into different location.

Here's why I've created this stitch: As the name suggests, this stitch looks exactly the same on both sides of the fabric (something very rare in crochet!) Furthermore, though not being square shaped, the stitch has square proportions, so patterns can be drawn on regular graph paper. It also stacks the stitches perfectly atop each other, creating strong, straight vertical lines and keeping the design true to the graph. It creates a very thick, solid, and stiff fabric.

 

To keep the stitches very straight and solid, insert the hook lower down into the V, in the middle rather than at the top directly under the bar. It is a little more difficult to get through all the yarns that are in there but it makes a better stitch.
