Working with synthetics to make this 9 x 22 design
The material is a 3 mm multi-filament polypropylene with a mixed synthetic core made by Wellington. I think it is more like a 2 mm diameter as the finished piece is a nice middle of the range "medium" size coming in at 7 1/2" circumference.
Ends are stitched and not melted so there are no scratchy or hard nubs.
