Block Stitch or Dice Pattern

This pattern has three variations, I just don't know where I placed the third one. When I find it, I'll update this post.

So, the top picture is the garter stitch variation and the bottom one is the seed stitch variation. (The one missing is the Knit-Purl Block variation.)

Barb says that this is the simplest form of knit-purl checks and that all three consists of knit stitches, with the variations being either of garter or seed stitches. The one that I left out, the knit-purl variation, Barb claims it looks the same on both sides, which hasn't made it any easier to find among my pile of swatches.

Oh, a little side note, the color isn't messed up, I used two different yarns for the swatches. The first one is a made of Cascade Yarns Pima Tencel, leftover from when I knitted this. And the second is Tahki Classic Cotton.
I forgot how totally enjoyable it is to knit the pima tencel. Great summer yarn to work with, very cool to the touch. I would dare to say even refreshing to knit with on a hot summer day.
And the cotton is a really stable. I hate it when cotton yarn is so loosely spun that it unravels as you are knitting it. Not to mention pretty affordable, with a great range of colors.

Update



I found it! Above is the knit-purl variation of the Block Stitch or Dice pattern. It is knitted with the Cascade Yarn's Pima Tencel.
