The very fist quilt I made to give away as a baby gift was a simple "Trip Around the World" pattern in which a bunch of small squares are arranged so that the 4 fabrics I used made repeating diamonds through the quilt. All diamonds. So I quilted straight lines through the darker colored diamonds, but when I tried to quilt the through the lighter diamonds, they were rectangles???? Turns out I had turned one of the 4 huge blocks that makes up the quilt sideways when I sewed the top together. Yikes. I did some creative quilting and then just gave it to the couple anyway. They loved it so much they hung it on the wall instead of using it. I call it my first piece of abstract quilt art!!!!!!
