This stitch is typically used for leaf patterns. It throws out a padded effect on the motif. The stitch looks a bit difficult, but has no complications when you start to stitch. In fact, you will enjoy it as you see a beautiful, richly filled leaf emerging as you go along.

I have used a leaf pattern to illustrate . It is divided into three lines, namely, A, B and C, which will act as the respective stitch lines.

Fig 1: Bring the needle out through the topmost tip of the leaf. Now, take the needle in through B at a point that lies half way in the stitch line. Bring the needle out through A, at a point that lies horizontally parallel to the point on B.   Fig 2: After pulling the needle out, take the needle through C and out through A, as shown in the picture. Pull the needle out.

Fig 3: We again put the needle through C and pull it out through A, only this time, from the bottom of the stitch on B.   Fig 4: Continue this process of stitch. Each new stitch between C-A falls right under the previous stitch.

Fig 5: The padding effect takes place as we keep stitching.   Fig 6: Half way through, our stitch would look like this. Continue the process to finish the leaf. The stitches done over the other half of the leaf would fall over the existing threads from previous stitches. This adds to the raised effect of the leaf.
