Like Verdun, no templates. Pittosporums grow from a single stem, and so lend themselves well to having a single trunk, and then you just go for whatever shape foliage you want. Lonicera nitida are suckering, and produce multiple shoots at ground level, so a single trunk wouldn't really work, they work better as a block shape of some kind. Both plants will quickly grow out any errors you make. You may need a frame if you want an object (animal, etc), but otherwise you shouldn't need one just to make the usual domes/cubes/pillars, etc. It's more fun freehand!
Here are mine
