100 Stitches - Step Stitch

Time again for 100 Stitches! This gorgeous stitch is the step stitch: It looks pretty difficult to do doesn't it?! It actually turned out to be easier that I thought it would be. At least my version :)100 Stitches was a little short on some details. I had to just assume what was meant and go with that!The first step is to draw some guidelines. 100 Stitches suggested that you make two parallel lines, approximately 1/2" apart: Now, stitch the two lines with chain stitch. Make sure the stitches are exactly in line with each other.For the next steps, I chose a contrasting colored floss so that everything would be easy to see. Come up through the fabric through the second chain stitch on the left side:And back into the fabric through the second chain stitch on the right side. Work straight stitches across the two rows of chain stitch...
linking every second pair...of chain stitches:Making a nice ladder look:I am only stitching a few lines for my demonstration:
Three should be enough: Now come up through the fabric right below the left side of your first straight stitch:Make sure your floss stays on the left hand side of the needle and that your needle is pointing down. Go under the straight stitch and: whip around the straight stitch about four or five times, until you are at the center of the straight stitch. At this point, insert your needle 1/8" above the straight stitch and bring it back up right below the straight stitch forming a vertical stitch: Now making sure the needle is pointing up, and that your floss stays to the left side of the needle:
start whipping around the straight stitch:
about four or five times until you are at the right end of the straight stitch. 100 Stitches didn't specify how to finish this off so I just made an extra whip around and went back into the fabric and secured my floss:Move down to the next straight stitch and start again:When you reach the center, pass the needle under the middle vertical stitch you made on the straight stitch above you. Just pass your needle under it and pull down:Now start whipping around the straight stitch just like you did before - remembering that this is the second half of the straight stitch so your needle is pointing up:
Finish that and start on the next straight stitch:Just keep going until you have completed all of your straight stitches:I hope that I did this stitch correctly, I would appreciate any advice or critiques! I also included a picture of the back of my stitching:This stitch is #65 and is in the composite stitches section of 100 Stitches.
