Use the Magic Wand, keeping the settings on the control palette as they were before, and click in the area outside your petals. Use Selection/Invert, followed by Selection/Modify/Contract set at 1 and Selection/Modify/Feather set at 1. Use the left of the copy/paste buttons (or Edit/Copy) to copy the shape to the clipboard. Paste another copy of the shape as a new layer into your rosette image. Use Selections/Select None.

Click on the rotate button, or use Image/Rotate, and the settings shown below.

Use the moving tool to move the new image and line it up with the original one as shown on the left. The first petal of this copy will cover the last petal of the previous copy.

Paste another copy as a new layer, rotate 180 degrees right and line it up with the previous one, and finally paste a last copy, rotate 270 degrees right and line that one up. Your image will now look like the one on the right.

The one complete petal at the top looks wrong, so take the erase tool, with the settings shown on the right. Make sure that layer 4 is the the selected one on the layer palette, and carefully erase the parts of that petal which cover up the ones underneath. Be careful not to erase beyond what you need to, especially near the centre. Your image will then look like the one below.

Use Layers/Merge/Merge Visible so that you once again have only 1 layer, called Merged. Save your image again.

Take the Magic Wand, with the settings you used before, and click in the image outside the petal circle. Use Selection/Invert, Selection/Modify/Contract set at 1 and Selection/Modify/Feather set at 1. Copy the image to the clipboard and paste it back as a new layer. Use the moving tool to move it exactly above the original copy, so that there appears to be only one copy.

Use Selection/Select none.

Make sure that Layer 1 is the selected one on the layer palette. Use Image/resize. In the settings box, set Percent of Original to 75. Make sure that Resize Type is set at Smart Size, Resize All Layers is unchecked, and Maintain Aspect Ratio is checked. Click OK.

Without moving that image on Layer 1, use the Paste as New Layer button again, to paste another copy of the full size rosette in the image. Make sure that Layer 2 is the current one and move the new one till it exactly covers the original rosette. Use Image/resize again. Set Percent of original to 50 but keep all the other settings as before. Click OK. Your image will now look like the one below, and you should once more save rosette.psp.

On the layer palette, click on Merged to make it the currently selected layer.

Use Image/Noise/Add. Set % Noise at 50, check Uniform, and click OK. Use Image/Blur/Gaussian blur, with the radius set at 2.00.

With the royal blue still set as the foreground colour, use Image/Other/Hot Wax Coating.
Use Colours/Adjust/Hue Saturation & Lightness. Set Hue at 0, Saturation at 100, lightness at 26 and click OK.
Use Colours/Adjust/Brightness & Contrast, with Brightness at 15 and Contrast at 6. Click OK.
Your image now looks like the one below.
