@talkingskunk I didn’t realize that the curve was so snakelike and not flat.
What you can do in your case, is to give the curve a Bevel and then convert it to a Mesh again and Instance a single scale to its Faces:
Of course first take care of the spacing in the Curve and make sure you have the correct resolution.
Important: if the orientation of the scales is wrong, first unparent the scale, the rotate it in Edit Mode (or Apply the Rotation) then Parent it again.
