I have the following illustration:
I want to try just putting a small stroke that goes around the outside of the drawing, however when I do select all and apply the stroke, it obviously strokes the inner parts of the drawing (for instance the mouth, eyes, dimples, etc). I've tried merging all of the layers, but it doesn't work. Does anyone know how to do this or is it even possible? Thanks.
Select all; Group; with the group selected in the appearance panel, Add a New Stroke amd drag it below the Contents line. Set to an appropriate size remembering that it will be partially covered by the objects above.
Damn, just a minute too late.
With the Group and Layer way, you can change individual paths and have the outline (in a new sense) change accordingly, so it may be seen as a question of choice of options.
With the Layer way, you have a further blessing or curse: there is no need to Group, and you can add new paths freely and even create new pieces of artwork (without having to drag them into the/an existing Group); obviously, everything on the Layer, however unrelated, will be treated in the same way, with the same outline.
