It’s called planning. Think how you are going to make with the available tools before starting. If you are using an old version of blender it will be more complicated. For complex shapes try using curves

Thanks
but curves still need faces?
i put a plane in front of the shape. subdivided and deleted the unvanted verts then just moved the verts to the right places.
worked very well
