These exciting, multicolor threads are a masterful blend of different colors within the same range of tone and intensity, with random, subtle color changes every 2-1/2 to 5 inches! No other thread does this! Our 30 Wt. Cotton thread is slightly thicker than your standard 40 Wt. quilting cotton. This allows your quilting or appliqué to stand out from the crowd! All Sulky Cotton Threads are premier quality, long staple, highly mercerized Egyptian cotton with a matte finish to create a soft, warm, natural look and feel. ALL our cotton thread comes from 100% Egyptian Cotton that is grown in Egypt. Most critical to its quality is that it is dyed and finished in Italy.
