Simple (but attractive) block with raised stitches that look like arrows pointing in all directions.

Worked from the chart, with joins in the corner.

While crocheting the second one, I realized that I’d worked my second and third rows of trebles into the wrong stitch on the first block. (They were one row too short.) Since this pattern works up so quickly, I frogged back to the second treble row and redid it. Worth the extra effort to get it right, because the block looks much nicer with the taller (fully extended) trebles.
