In the comments of the photo the creator says she made the base using Earlene's instructions from her website. I went to that site (www.earlenescakes.com) and found that the Puff Base Instructions are available for purchase at this URL:
Hope this helps!
i have seen simple, free instructions kicking about - these boards have been used on lots of cakes, maybe send out a few polite PMs, see if any of the people that used them, made them, and are willing to share?
I made one of these and I used a metal wreath form..... you can get them at most any craft store....... I wrapped it in blanket batting, then in cheap satin or taffeta fabric....it was really easy and FUN !
This one is a little different than Earlene's, but just as lovely: http://www.flickr.com/photos/the-icing-on-the-cake/3068449094/
