You know, you could do this. Believe me, it wasn’t hard.
The graph from the pig (see below) was one square to one inch, and most suitcases are standard sizes, so it would probably be in proportion to your suitcase, although if you have pockets on the outside of the case, you may have to get creative and put the face on the upper pocket and the dress on the lower one.
If your case is light-colored, used a soft pencil to sketch in the outline; if it’s dark, get a white pencil. The best way to transfer a graph drawing is to first draw the graph squares on the thing you’re transferring the drawing to, which in this case would give you a checkerboard background which could be kind of snappy. Once the graph is on–one inch squares–then you match the lines on the graph drawing to the lines on the suitcase. It doesn’t have to be perfect, it just has to vaguely resemble a pig. And this drawing is so simple, it’s mostly squashy circles anyway:
Note: I added the feet later, but they’re just a curved line at the bottom of the case.)
Once you have the drawing transferred to the suitcase in pencil, go over it in permanent Sharpie. Don’t worry about a few messed up lines, you’re going to make them a lot thicker on the finished pig: On a black suitcase, forget the Sharpie lines and just paint the pig on in white, then add the pink and black details on top of the paint with the Sharpie
The pinks in the dress were done in rose and pink Sharpies.
If you have a light colored suitcase, go back over the lines, making them about 1/2″ thick. You have some leeway since you’re going to cover the pig in white primer. If you’ve already painted the white on your black suitcase, just make the interior lines the 1/2 inch.
After that, it’s just going over the thick black lines about a thousand times (okay, about six times) with the marker, and painting in the white areas in thin coats (about four) so that it doesn’t bead up. And you’ll have a pig. Oh, and put a little dot of white in each eye for a catchlight. It makes a huge difference. (No, I didn’t put them in Krissie’s Pig’s eyes yet, I’m still going over lines with marker.)
Now I’m really intrigued about doing a white pig on a black suitcase, but I have all this drywall to paint. And copy edits. And a book to write. Hmmmm.
