Well, this afternoon, after a long while searching for a pre-made nature notebook cover (for a binder with a slip-in see-through cover), I decided to go ahead and make my own.
I use Photoshop Elements for these sorts of endeavors, relying on free downloadable brushes to create the natural elements you see in the background.
Of course, my personal copy includes a text box that says it is our family's nature notebook. I left this example blank so that you can download the file for your own use below.
I forgot how much I enjoy creating images like these on PSE. I hardly ever have the time to tinker around, though. I hope the download of the jpg file doesn't take too long. Click on the link below to download and either save or print out. I think I have it to the correct size so that if you print from the image online (PC: choose File/Print) it should fit onto an 8.5x11 piece of paper. IF you have trouble, drop a line in the combox.
