The silk is from the Bombyx mori silk worm, often referred to as "mulberry" silk.

Each skein is 5 yards

--All widths of Treenway Silk's ribbons are woven with selvage edges.  The selvage edge can hold up to stitching on fabric or being pulled through canvas.
--The silk used is the highest quality reeled silk which still has the sericin in it.  The sericin acts as a natural sizing. 
     --The warp (length-wise) threads are two strands of fine silk which are twisted together. There are 300 fine warp threads per inch.
     --The weft (cross-wise threads) is a single silk strand.
     --The ribbon is woven in plain weave, where the weft thread goes over and under each individual warp thread, all the way across the ribbon, giving a strong, stable ribbon.

Hand-dyed in Colorado--color fast.
   We use acid dyes for all of our silk dyeing. 
   We heat the silk until all of the dye is absorbed.  We allow the silk to cool down overhight.
   We rinse the silk until the water runs clear.

Wash instructions:  Using a drop or two of a mild soap, wash in cool or COLD water for no more than 5 minutes.  Let dry.  Iron, if desired, using the Silk setting on your iron.
