I printed the border pattern from the Cd on to an A4 piece of copier paper . The border appears on the righthand side of the landscape orientation of the paper. I then measure how far in from the far lefthand edge the border finishes and the same from the top, right and bottom edges. E.g. Lefthand edge 175mm, 35mm each top, right and bottom. I put these measurements into my printer and then using parchment paper print the digi image to 'fill the page'. As I have already reduced the printable area and placed it where I want it then the border will fit perfectly around the image. The border is already on the piece of copier paper ready for me to trace and emboss on the parchment. I use this simple technique to place all printed images to parchment so that I can size and place them where I want them. If you have a complicated grid pattern it is always sensible to make a template and then do the measuring for the printer.
I am a mite late this week posting my DT card and in visiting our challengees as I have been away. Good luck in the draw to everyone.
