If I didn't carve Acanthus leaves I'd be out of business.
With this last minute addition to a job I figured I'd show how I go about doing a set of left and right onlays. It's not too in depth but hopefully it gives you some ideas to try.
In this "installment" I'll show the basic layout which is very common to all designs. Lets face it, they are merely variations of one another and can easily be adapted to any situation. That's what makes this design so versatile and useful when you have to fill up a space with some sort of carving.
True to any design regardless how simple or complex is the basic line that flows through it. I always lean on a version of an S curve. If you stand this design on end you'll see it immediately. This design lets your eye flow from one end to the other and keeps it moving without break. Also it's a natural shape that if you stand it with the larger end on the bottom you can almost make out a Swans neck, head, body and wings sweeping back from it. Trust me, it's there.
Now most designs of this sort start from a curl of some sort and spiral out from it. I'm keeping this basic so the center of my swirl is a simple round button type shape. I just loosely freehand start a spiral and let the design expand from there. In this case it starts from the right , gradually opens and sweeps across to what could be a base line and then returns on itself.
As the design expands I keep sweeping lines from it to give me a general flow of the design and where it's going and this is where I'll build additional leaves.
Now most designs you see commercially done tend to look like they were done with a compass. Don't do that. They look too rigid and stiff. And if you think about it, an acanthus is a sort of lettuce looking plant. If it were coiled or draped gravity would play on it and not allow it to curl in a perfect circle. In this case the center button of the piece adds "weight" to the look and hence makes it droop. The center isn't in the center as you will see.
This also allows the piece to be used in either position. In one case the center of the design will droop and the rest of the design sweeps away from it. From the opposite view the rest of the design will fall away from it.
In these sequence sketches you can see the elements of what I was looking for. I just let my hand flow with the pencil and let the lines fall gracefully. As the design starts to reach across the page the lines gradually shift their direction from wanting to continue to follow the spiral to starting to stretch to the terminal end.
At the terminal end you 'll see that the leaf wants to curl again,, or is curled and wanting to straighten out. Think of this as how a fiddle head fern grows.
Maybe I'm writing too much and trying to let you in on what's going on in my mind and I should let the sketches talk for themselves.
