Jeanine- I have never seen anything mentioned about the backing either. I wonder if the museum has any information.
I am having a lot of fun reading everyone's posts. There are some great tips and helpful ideas on here!
I ordered my colored fabric last week.
Today I went into town and bought the background fabric.
I am soooo anxious to get started. Meanwhile I am playing with the software and trying to be patient. Hope that package comes soon!
