|Deepika's pressing article made me think of one item I used for long seams... A towel.
To keep the seam allowances from showing when pressing open long seams (like on pant legs or sideseams), you can use a tightly rolled up towel. Tie the ends with some fabric scraps and you've got a seam pressing roll (I'm not sure what this tool is called, but it sure works well). Another good seam press would be a long dowel, cut or sanded down to keep one side flat. My BIL finally made one for me.
Also, for some low plush fabrics (like cotton velveteen, crushed velvet), you can use a really thick towel as your "velvet board" and it'll prevent the nap from flattening out. Just be sure not to press too hard.
