I've used it many, many times over the years- I love the stuff! first time was a water color quilt class about 9 years ago- I've done lone star quilts with the same product (QuiltSmart has many different patterns that use the same interfacing with different 'grids/patterns') I've made many bed quilts (I don't generally do wall hangings) with it- I've never had any problems with stiff quilts- it washes up beautifully-soft- great drape. I generally always have a bolt of it in the closet for when ever I want to work on something with it.
