inlays

Does anyone know of a good program for making inlays of different
colored wood? I have been trying vector and although I can draw good
pictures I have an incredible hard time to get them to chain together
when theres a lot of curves. the last pocket Ive been working on for 4
days and cant get the pocket to work even though it selects all from
anywhere on the drawing and appears to be chained. its all on the same
layer.
