Open a new Photoshop document, mine is 480×480 pixels.
Using your Pen Tool create a shape like you see mine below.Now create a new layer, CTRL+click the shape layer you just created and then go to Edit > Stroke, set the width to 2 px and color to white and click OK.

Using a soft Round 65 pixels brush, delete the right part of this layer, until you obtain something like this:Now right click on the layer in the Layers Palette and apply a gradient to this layer from #ff3237 to #ff9b01:Duplicate this layer, on the new layer apply a Gaussian Blur filter with the radius set to about 4-7 px then duplicate this layer 2 times.Select the last three layers you created and merge them (you can go to the Layer menu and choose Merge Layers or CTRL+E).Duplicate this layer again and choose Edit > Free Transform and then right click and choose skew and skew it to right like you see in the picture below:Now press CTRL+ALT+SHIFT+T and you should obtain something similar to this:Group the last 3 layers and then duplicate the group and go to Edit > Free Transform and choose Flip Horizontal. Arrange the 2 groups like you see below and you will obtain something that starts to look like a flower:Here you can see the 3 layers that a group contains:Make a selection aroud the flower:Create a new layer and fill it with a color;it doesn’t matter what color, mine is white. This layer should be arranged below all the layers.
