You don't need to move and take my class to learn that! There is an excellent reference in print that you can buy, which tells step-by-step how they were made. It is a book called The Top Hat: An Illustrated History by Debbie Henderson, and in its appendices Henderson reproduces in full instructional literature that Hat Life Publications put out in the 1940s on the methods for making standard and collapsible toppers, to make sure that info wasn't lost. Pick up a copy and give it a go! It's the reference that Adrienne used to make hers.
