I have seen several picture posts here where the poster indicated they did trapunto but it was only pics of the finished product.
Here is a link to a post I did several years ago, where I incorporated trapunto technique but added quilting to the area before cutting away the excess batting and then reloading the wallhanging. Many LA quilters are loading double bats to give the appearance of trapunto without all the tedious trimming involved. It makes for a very heavy quilt though. Works really well for wallhangings.
