I am working on a 16 inch polystyrene pillow(only one I had available, other pillows are full), but I don't recommend that size. Not enough room for bobbin space as you can see. Use 20 inch or larger. The bobbins I am using are Belgium style continentals and one lone Bayeux bobbin. The thread I am using is Oliver Twist varigated for the leader pair and two passives and gold metallic Oren Byan for the left hand edge pair.
