If you make a rectangular selection in Photoshop, and you find it’s not big enough you COULD make it bigger by using Select > Modify > Expand. This will work if you only need to expand by about 4 or 5 pixels, any more than that and you’ll notice that the corners start to become round.

So here’s a better way to expand;
1. Make your selection.
2. Press Ctrl+T (win) or Cmd + T (mac) to bring up the Free Transform bounding box.

3. Simply click and drag one of the bounding box handles and pull your selection to the required size. Press Enter or Return to complete the transformation and voila! Nice crisp corners on your expanded selection.

You can transform any selection of any shape in this way. I’d love to hear your selection tips, any you’d like to share?

Have you ever needed a bit of pattern just exactly the size of your selection? Here’s a tip on how to get a selection from one file into another:
-Make your selection in document 1
-Make sure you have the rectangular or elliptical marquee tool selected
-Position it inside your selection and make sure it shows a little rectangle
-Drag the selection over to document 2 and position it as you like
-Copy, move to document 1, and paste! Ta dah!
