Open a new canvas, 600 pixels by 600 pixels to give you plenty of space. Draw a frame the size you wnat it to be with your Rectangle preset shape (foreground colour white or colour of choice, background colour closed off). Make it fairly wide because that gives better results (i had my line width set at 70). Convert to raster and apply any effects you wish to.
I used a Super Blade Pro preset for the left one and a photo of a rusty surface for the other one.
Select – Select all – Float – Defloat, then Distortion effects – Curlicues. I used the follwoing settings: Number of columns: 4, Number of rows: 4, Radius: 100, Sttength 100, Symmetric unchecked, Clockwise: checked for the one on the left, and 3 columns, 3 rows, Radius set at 77 and Strength at 100 for the one on the right.
Select none, and then carefully erase the curls. Add an inner bevel using PSP’s own bevel effect or using the Eye Candy beveli filter and you’re done.
