I have seen them on so many Beachy wedding cakes. Some one just contacted me for Sat. because their cake decorator canceled on them. Where can I get them in a hurry?
I saw a tutorial on how to make them a few weeks ago, but I can't remember where. You could also search for directions on how to make real adirondack chairs and use that as a guide.
Here's a tutorial for another beach chair I just found when I googled it.
I may also have to make one or two for my mom's birthday cake next month.
