Hi Miri,
Here's what worked for me and what I got from demonstrator support for info on this one.
Using the sweet treat box template as your base (see attached) you would then cut away the tabs and top piece that would create the gable top.
Then slightly off center cut away a small square area for the "window". Next craft a small regular box top about 1/8" to 1/4" slightly larger than the exact square opening and Voila you have your Catalog box. The almonds are placed in a cellophane bag but you could adhere some acetate window sheets and then fill the box from there.
SU is planning to release a template at some point in the patterns area for at least the top if not the whole box.
Hope this gives you somewhere to start.
Have a blessed Easter - Jean Fitch
