Here it is using 5 different designers from the current BYOC - Lynn Grieveson, Paula Kesselring, Just Jaimee, Mommyish, and Bella Gypsy. Oops, I also have a bit of washi tape from a Designed by Soco kit. (I meant to remove that when I added the banner but was having issues with getting this the size I wanted. So now it stays!)

Sorry I missed your posts @scribler & @GodBlessAmerica but @IntenseMagic definitely has steered you in the right direction! I can't wait to see what you do!
