Reply To: Why does the decorative curl from my bezier curve have an uneven thickness (thick at one end, decreasing to very thin on the other)?

Ok. Your Taper Object (Bezier Curve.003) is messed up and should lie flat in the X,Y plane, something like this (make the changes to that curve in Edit Mode):

Now it should work as expected (these Taper Objects can be a bit tricky to get right…):

I also adjusted your snapping settings because that was only affected by Scaling.

Let us know if there are more problems.
