You will be dazzled and amazed at the intriguing results you will get with Sulky 30 Wt. Cotton Blendables thread. 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 1/3 thicker than your standard 40 Wt. quilting cotton. This allows your quilting or applique 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, which is why you see "Made in Italy" on the spool.
