This beautiful floral pattern was created using (RMW) Rustic Moire 100% Wool Threads from Spain. A new feature the Efflorescence pattern will now include are the Valdani Threads and DMC Floss color code lists, along with the original Rustic Moire Wool Thread list. This provides you with several thread options if you choose to substitute the RMW threads in creating this design and obtaining the necessary supplies more accessible.
