The rose to the left is from an internet pattern. I just used part of it to get a feel for the stitch. I've done cross stitch , and although I know Assisi work in principle, I've never stitched it.
I have trouble recognizing negative space, so I was relieved to learn I could outline before working the background if I wanted. Next I had to figure out what to use as a design. I couldn't get past the association of St. Francis whenever I tried to think Assisi .
I wanted some color for the background but didn't have the ambition or time to attempt an outdoor scene. I went for a stained glass look , contemporary, with a hint of a cross and just the suggestion of a church window. Most of the background filler is cross stitch done with single strands of cotton floss. As you can see I ran out of fabric length.
