This is the yarn I used. I chose this yarn because this blanket doesn't work with the stitches it works with the holes created. It is hard to see the stitches with this yarn so I wouldn't suggest it for a normal crochet pattern but it works for this blanket.
Once you have your chain foundation, you need to chain two to start your next row. (As I said in my double crochet post, some crochet three t start the next row I crochet two). Since you use two chain stitches to create the wall of the next row, you want to skip those two and one more. In the forth chain stitch you want to create one double crochet and than another in the same stitch. Once you have your two double crochets, or V stitch, you want to skip one stitch and start over in the next one. Continue this to the end. For the last stitch of all the rows you want to create one double crochet and then chain two stitches before continuing.
This is what one row of V stitches looks like.
Once you have the first row, you want to stitch your double crochets into the holes left between the V stitches, this will cause the pattern to grow like a brick wall lay out.
This is what it looks like with normal yarn.
Continue in this same style until you have the size of blanket you want. I am creating a baby blanket so I only used two balls but you can add as many as you want. (For a bigger blanket I would also suggest adding more chains to your foundation).
This is a close up of my finished blanket. I loved this blanket so much I created a pink one for a friend having a baby girl.
(The Yellow is called Lemon Swirl and the Pink above is called Peach Swirl)
UPDATE: This blanket became so popular that I was asked to create an adult blanket. With the baby blanket I chained 82, for this adult blanket I doubled that to make it 164. It is still the same process, however it will take more balls of yarn.
