You will need the tube I used here it is one of Noeska's and you will find her tubes here

Open the tube and add-effects art media effects-pencil

Settings-luminance 13, colour white, blur 1, intensity 10

Go to layers-new adjustment layer-curves

Settings as in the screenshot-you need to click on the line to make a node so that you can adjust as you wish. If you use another tube these settings may not be the right ones so experiment until you are happy.

Go back to the tube layer and add a drop shadow of your choice.

Duplicate this layer but work on the bottom layer.

Effects-geometric effects-pentagon-default setting.

Before you start the next part I will explain that the colours or patterns you chose will look darker as they will be under the adjustment layer.

Click with your magic wand in the black pentagon. Add a new layer and flood fill the selections with a colour of your choice. Add a drop shadow to this layer then select none.

Add a new layer-flood fill this with another colour or pattern of your choice-layers arrange-send to the bottom

Layers- merge visible.

Add a picture frame or border of your choice.

I used the varicoloured one from PSPX-I added it twice and the second frame was flipped. Try experimenting with the various settings on the frames it is amazing what you can create. I added a border -size 1 just to finished it off.

Resize as you wish and add any text you like.

I resized mine by 80% the adjust-brightness and contrast-clarify-setting 2-0 or what you are happy with.

That's the tutorial finished-I hope that you enjoyed it
