I'm seeing various options for windows. I tried the isomalt route and thought it was labor intensive and expensive. While I was finally able to get a good result -- clear and not yellow -- ultimately the isomalt clouded, either immediately or months later. I see that there is a spray -- glaze spray -- that can be used to prevent this, but it adds cost. Do the candy melt windows stay clear and non sticky?
I tried mixing and pouring gelatin windows but that was a complete bomb and I never got the hang of it. Ready-made gelatin sheets seemed like a viable alternative, but they always have that diamond pattern grid, which is fine for a Gothic build but not necessarily other architectural styles.
My final idea and most interesting option is Cello sheets from Icing Images. These look exactly like plastic report covers, but are edible. I purchased them but I have not applied them to a gingerbread house to see how they hold up. Has anyone else tried Cello sheets?
