Ok, lots of people request sigs, simple sigs which need only require basic selection and composition skills. Here I shall outline the Quick Mask method.

In my example I will this image:

Example 1 - Quick Mask Selection

This technique makes use a of a little known mode in Photoshop called Quick Mask.
The icon is located on the lower half of the tool pallete below the foreground and background color options. You can also use the shortcut Q to access it.

Step 1
Firstly, you will need to make a rough selection of the object using the lasso tool. I prefer to use the polygon lasso, but the normal lasso will work just as well.

No need to be accurate, just get an idea of the outline of the object like so:

Step 2
Now activate Quick Mask mode (Shortcut - "Q"). You will now see that the area around your selection has been masked with a (usually red as standard) opaque colour. This is just another representation of your selection and should look as follows:

Now, to start the magic you need to select the brush tool.

Step 3
Now to start refining the selection. First off you should realise the background/foreground colours have changed to Black and white.
Black add's to the mask (adds red opaqueness) and white subtracts it.

The aim is to use the brush tool to paint round the object to get a smooth and accurate mask around it. You can switch between the black and white using the arrow on the top right to them like so:

You can adjust the brush however you like to get the desired effects by using the brush tool options under the main program toolbar like so:

Now just keep adding and subtracting the mask until you feel happy you have totally masked the parts of the image you do not want. You can check your selection anytime buy just hitting the Quick Mask button or pressing "Q".

You should have something that looks like these:

Selection:

From there you can cut the image from the background by using ctrl+x and then ctrl+v to pase it into your new image. Easy!

to be honest you should have made many pictures of the tut a shrunken original, not a blown up version of the smaller image.
