Appleton wools come in 2 types: Crewel Wool (2ply) and Tapestry Wool (4ply). Tapestry wool is usually used on 12hpi canvas, but, depending on the stitch, can be used on 10hpi. For 14hpi or finer canvas we would recommend crewel wool. For embroidery work we would recommend crewel wool as it will lie flatter than tapestry wool.
With crewel wool you can vary the number of strands you put through the needle. This depends on the stitch, but usually you use 3 strands for 12hpi. Because you can use more than one thread in the needle at a time you can mix colours in the needle for blending or interesting effects. Some kit designers use tapestry and crewel wool in the same kit for this reason.
Appleton wool comes in 3 sizes:
– Skeins (10 yards of tapestry wool or 30 of crewel wool)
– Hanks (equivalent to 6 skeins)
– Bundles (20 hanks)
