RIOLIS wool/acrylic embroidery thread has been used in their kits where great coverage and depth of colour bring a design to life - and now crafters can use these great threads in their own designs. Each packet contains ten skeins, each 20m in length. This is a non divisible thread, and should be used with 2 or 3 lengths to cross stitch on 10 - 14 count aida fabric.
