This is my creation.  I am using the wonderful kit Last Night by Bibi's Collection that you can get here. I started with a 700 x 700 and am working with PSP X2 Ultimate.  I used papers 6, 4, and 11 from the back.  I used masks RBsummermask4, MisfitsChoiceMask 4, and MythMask31 from the back.  These masks are from Creative Misfits Creations here.  At any time, you can gradient glow and/or drop shadow in the process.  Element 27 was placed in a corner in front of the last paper to show what I wanted, duplicated, mirrored, duplicated, flipped, duplicated, mirrored, and merged all the layers down to have all four together.  Next, is the second paper.  Element 73 is in front of that placed to show parts where you want.  Element 72 is in front of that.  I placed it in a corner, duplicated, mirrored, and flipped, so I could have them in opposite corners to show.  Element 33 is in front of that.  I placed it on the side where I wanted it, duplicated, and mirrored to have them on either side.  Element 58 is in front of that.  I placed it in a corner, duplicated, mirrored, and flipped it to have them in two opposite corners.  Element 3 is in front of that.  I placed it where I wanted it, duplicated, and mirrored, so it is like an X on the image and show.  In front of that, I have the last paper.  I put the effect of blinds on it.  You can do it however you want to look.  I put element 64 in front of that to look like I wanted.  Element 34 is in front of that where you want it to look.  Element 31 is placed like a moon in the front of the cloud element and behind element 7, so you can move them how you want them to look.  Next in front of element 7, I put element 5 in a place I wanted, duplicated, and flipped it.  You can place it how you want.  In front of that, I have element 56.  From there, you put the tube you want.  I am using the beautiful tube of Alex Prihodoko you can buy at PFD here.  You need your own watermark, the artist's copyright, and the name you want on it.
Below, I used another Alex tube, an Arthur Crowe tube, and a Barbara Jensen tube on the ones I made with the same background.  One has a couple more elements in it
