I created this background lace for 12x12 in about an hour the other day. This is an image of what it looks like - I cut it in navy blue and laid it on a large white folder for visibility.
It took about 10-15 minutes for the build and then about 15 mins to cut because of all the TINY pieces it had to cut out.
I am quite impressed though. It is the first big file and cut that I have done with my Gypsy and the Expression
