Donna,

Welcome!

Great question! It depends on the size of your beads. There are charts for measurements of strung beads, beads stitched per square inch and rows per square inch. I haven't yet been able to find something specifically measuring beads per inch in peyote stitch, so here are the references I did find.

For number of beads per inch as strung and number of beads per square inch, you'll find that info here:

For rows per square inch, you can find that info here:

If you do find what I can't seem to, please stop back and give us a link!
