Under Libraries in EQ7 there is a Layout Library. You copy from your Sketchbook the layout you want to save and paste it into My Library tab in the Layout Library just as you would if you wanted to save blocks or fabric. It will only save the actual layout not the fabrics and blocks that are used in the quilt - if you want to save those as well you will need to save them in the My Library tab under Block Library. Does this make any sense? lol??
Once you save it there it will be available to any other file
