Plan to use a 1-1/8" wide rick rack appliqued on a baby quilt border. I know these are often used on purses and bags that are not usually washed. It's 100% polyester. I don't usually pre-wash my fabrics (I know - this is an ongoing debate) but am concerned it may shrink. Maybe I'm thinking of old cotton rick rack from my sewing days in the 1960's :-)
