I thought I might share this version of T-stitch, as it's the only one I've ever seen or used - until recently. It's a great stitch where just a little bit of texture is needed, but not overwhelming. I do these in two colors when drawing, simply to illustrate the "traveling."
The green horizontal is worked first, from right to left, and then the blue back across from left to right. It's extremely easy to visualize while stitching - the blue stitch is made from lower right to upper left, into the "green" stitch, and it forms the "T"
ADDENDUM: I just had an AHA! moment - that Sea Grass will be gorgeous used in T-Stitch! - great texture, I'm sure. If you haven't already looked at Thread Gatherer's web site for the Sea Grass colors - do go there.
BACK TO T-STITCH: I've been using this version of the stitch for about 12 years, and was unaware of another one by the same name. After looking at the ANG version, I can see the "T" clearly - but it creates an "open canvas" background, which is interesting. Maybe we should call them "T-Stich Open and Closed," as mine covers the canvas. I see other possibilities with the ANG version, so have to go play with it a while.
