When you are ready to begin rolling the strip into the rose shape, tie the threads together at the end you were gathering from to stabilize the end. Trim the threads so that they are about 4 inches long (I used these threads to help stabilize the center as I was rolling and stitching the flower by holding them in the palm of my hand with my pinky). Fold the beginning edge over about 1/4 inch and roll again, keeping the folds tight. With a needle threaded with a matching color, stitch through all of the fabric layers a couple of times. This is the core of the flower.
Continue rolling the folded fabric around the beginning folds, adjusting the tension of the gathers and stitching the edge to the previous layers as you go. This feels awkward at first and this is when holding on to that original gathering thread really helps to keep the core from slipping up inside the flower. Tug on those threads occassionally to pull the core back into place.
This photo shows the stitching on the back of the flower. When you are rolling the fabric strip, be sure to look at it from the front so that you can adjust the gathers for the look that you want. If you want your rose to look more closed, gather the strip less and pull it tighter as you go around. For an open rose, gather it more tightly and adjust the positioning of the strip as you sew it down. As the rose gets larger, the outside petals will look shorter because of the depth of the flower. To compensate for this, place the strip up on the previous layer slightly as you roll it and stitch it in place. Continue rolling the strip and stitching it in place until you reach the end. Secure thread and clip.
Here is the finished rose from the right side. You can see how the wavy cut edges give the rose petals more dimension. This rose is 2 inches tall and 2 inches wide.
I apologize for the blurry photo; my camera doesn't like taking close up pictures.
Here I have sewn the pin back to the rose itself using the holes in the pin back. The next step is to sew a piece of felt over the pin hardware and back of the rose. I felt this was more secure and attractive than sewing the felt on first and the sewing pin back to the felt.
