I bought most of it on line at different places. The one I used was a panel. Do a Bing or which ever search of "Beatrice Potter fabric".
One piece was a Book panel I cut up into quilt squares for another quilt, which to take a picture of before I gave it out.
If you are having trouble finding fabric, I will take pictures of what I have, if you want to purchase it.
