Yay for another installment of Tips & Tricks from the Q!
First up — creating waves. Misty Cato has a fabulous tutorial about creating wave shapes using PSE. This technique works in PS as well — the wave filter is in the same place: Filters > Distort > Wave. Trying playing around with the various settings in the filter to see how it alters your shape. 
You can make fat waves by using a fat rectangle, and skinnier waves by starting with a skinny rectangle.
Second — creating scallop or zigzag edges. Steph posted a fantastic tutorial about a week ago on The Daily Digi, with great instructions on how to create a scallop or zigzag edge.
And, of course, if you don’t want to do it yourself, you can find lots of fun shape templates on the market. I stopped by Sweet Shoppe Designs and found these:
Check their store for more shape templates.
If you create a layout using either of the tutorials, link me up so I can see — and be sure to pass along a thank you to Misty and Steph for their awesome tuts!
