On Aida 18 Cross Stitch Cloth you can stitch 18 crosses per inch (approx 7,2 per cm).
Aida 18 count fabric is made by little squares of 5 threads in both directions and four clearly visible holes at the corners. One hole for each corner of your cross stitch. Most Aida’s in our shop are made from 100% cotton. The fabric has been stiffened so that the threads do not move. This makes it a great fabric for beginning cross stitchers.
