Understanding counted-fabric density

Density sets physical scale

Fabric count describes Aida blocks or evenweave threads per stated length. Effective stitches per unit also depend on working over one or two. Keep the unit with the value: 14 per inch and about 5.51 per centimetre describe the same density.

Over-one and over-two differ

On evenweave, a chart square may span one or two fabric threads. Over-two halves the effective stitch count and doubles the motif dimension relative to over-one on the same ground.

Calculate, add margin, then sample

Use the figure below for the stitched area and add finishing margin on every side. Test the intended number of strands for coverage and confirm the fabric is square before cutting.

Try this example

A 70-cell chart on 14-count Aida measures 12.7 cm across. On 28-count evenweave over two it is also 12.7 cm; over one it is 6.35 cm. Add your chosen margin twice per axis. With 5 cm each side, the first design needs 22.7 cm of fabric width. Verify the real count before cutting.
