Hello, yes you could use any fabric you wish. But if you
use 14 count aida you would need for the verse and seascape together 25.6" x 9.5" plus six inches to the
height and six inches to the width for framing.
For the seascape alone would be 6.5" x 9.5" plus six
inches to the height and width for framing.
For the verse alone would be 18.3" x 8.5" plus six inches
to the height and width for framing. Hope this helps.
