|The DANKA brand IKEA ironing board (NAYY) is perfect for pressing curves. The 'pointed' end is not pointy at all and fits the bust curve of a princess seam quite well. Some ironing boards come to a defined point at the end. The edge here is very rounded, which makes it perfect for pressing princess seams.
I've posted some pictures of how I use the edge of the board to press the seam. Line the seam on the edge (not the top) of the board and use bursts of steam to mold the fabric around the curve.
In the past, I've used a tailor's ham and have never gotten a good press (probably due to user error). Having discovered how nicely the end of my ironing board works, I don't think I'll ever go back to the ham!
