Evenweave fabric is strictly speaking any regularly woven fabric where the warp and weft threads have the same thread count (number of threads per inch), and which is woven "on the square", so that a pattern of stitches worked on it will have the same shape as the design.
It has now come to refer more specifically to the finer fabrics, such as Belfast linen, which are constructed of seperate single threads, as opposed to block-weave fabrics such as aida cloth, where the fabric threads are grouped together, forming fabric blocks.
