Trellis stitch 1

The trellis stitch is the next challenge for February. I never tried this stitch before, but it was on my to do list for a few months. First I tried a rectangle in pink, but I pulled the thread to tight. The second one in green went well. Then I made a spiral trellis stitch in yellow. It's not as regular as I wanted it to be, but it's my first one. I think practice will make it better.
