I worked on this file last night and to be quite honest, I don't know how it will work for you when uploading to your computer...in Inkscape it was slow getting around b/c of the size of the file, I believe.  This file can be a gate fold card with the two ends folding into the center, having the rose borders against each other.  Or you can use as a mat for a card or scrapbook page....
