First, import the pixel image as a background:

Assuming the grid is 1/8":

Things seem to be the right size (if it’s some other size, scale up/down as necessary)

Use the polyline tool to roughly outline the design:

then increase the fineness of the grid:

and go into Node Edit mode:

and select nodes and drag them into a better alignment:

and repeat that for anything which is not lining up as desired.

Then, select nodes whichneed to be associated with curves:
