I accidentally learned something about the pencil tool in Photoshop Elements yesterday and wanted to share with those of you that may not already know this.  I'm using Photoshop Elements 10 but I'm sure it will work in earlier versions. 

Open a new document.  This first screen shot shows you where to find the pencil tool. 

After you've chosen your pencil tool, choose a color that you want to make a straight line with and then choose the size of your line, much as you would choose the size of your brush at the top left of your screen.  I'm using size "18" for this tutorial BUT if you're going to print this, I'd suggest viewing your line at 100% after it's drawn to see just how big it's really going to be.   Place your cursor at the area where you want to draw your straight line.  Click your left mouse button and hold.  Before starting to drag your line, also hold down your shift key and THEN drag out your line to the length you want it.  Holding the shift key ensures you're going to get a perfectly straight line.

Now stick with me because the next step is the coolest part of this tutorial!!

NOW comes the interesting part…………..you can also create more lines off this one single line as shown below.  Once you've drawn your first line, let up on the mouse key BUT continue holding down the shift key.  Reposition your cursor and click the left mouse key and there's your 2nd connected line!  You can continue this step and create as many lines and in any position you want.

Now I know there's also a line tool in Photoshop and Photoshop Elements, but it doesn't let you connect lines such as this using this technique.  So again, I'm using the pencil tool to do this.

I hope you enjoyed this little tutorial.  If you have any questions or if you found it interesting and helpful, I'd love for you to leave a comment for me!  Have fun playing!!

Thanks for looking and Happy Scrapping,
