A medium strong thread, a thin sewing needle with a large eye (the thread is directly threaded into the eye and the eye must be able to pass through the hole in the rocaille), a strong point (a thick needle or the point of a compass), scissors
Print or create the pattern and lightly pierce the points with the large needle or the point of the compass.
The stringing of the thread
Pull the thread off the bobbin (spool). Cut off the fine “hairs” at the end and string it into the needle’s eye.
You can use several types of stitch.
A prick stitch (double running stitch) – simple: it always looks the same from the front and the back. (Fig. 1/a, 1/b)
A back stitch – simple: several threads collect at the back. (Fig. 1/c, 1/d)
A chain stitch – more complicated: especially when sewing on rocailles. It is decorative from the back. (Fig. 1/e, 1/f, 1/g)
When embroidering, hide the knots and the ends of the thread in the rocailles. Try to create one embroidered line using a single long piece of thread.
The white line
Sew 2x R into the gaps between the openings. Sew 1x R onto the top in the right angle. When using the prick stitch (double running stitch), wait to sew on the top rocaille until you are adding the rocailles on the way back.
The gold line
Sew 2x R into each of the four top gaps in the arch and 1x R into each of the lower gaps. Add 1x R to the outer gaps on the arches forming a right angle. Sew 2x R into the outer gaps on the outer arches. Strengthen the arches by passing the thread through them while adding 1x R with the spike at the connecting point for the arches.
You can look for inspiration with regard to the white-gold Christmas rose in the Honey Poinsettia project.
