Shaker cards are so much fun both to make and to receive and contrary to what you might think they're actually quite easy to create. Also they stand out from standard cards because of the use of loose elements inside a "window".
This is how I make my shaker windows to use on cards.
Supplies:
Cardstock ( I used a piece of thick cardboard from a wine box)
Foam pads
Double-sided tape
Acetate
1 - Begin by cutting your window choosing the shape and size that will best suit your card.

2 - Put double-sided tape all the way around the reverse side of the window. This will hold the acetate in place and is a much quicker and cleaner way of attaching the acetate to the cardstock window frame. Place the acetate over the double-sided tape.

3 - Again, on the reverse side of the window, put foam pads all around making sure there are no gaps. This is important because you don't want your loose elements to come out when you shake the card.

4 - Choose the items you're going to put inside the window. They should not be too bulky as otherwise they might become stuck and not shake. You can use sequins, very small beads or even punched shapes.
5 - Choose the place on the card where you want your window to be and place your shakeable items there. Carefully, place the window you made on the card and make sure it's properly attached without any openings or gaps from where things might come out.
Depending on how you planned your card layout, your window can be used plain or embellished. If you're using stamps to embellish your window it might be a good idea to do the stamping before attaching the acetate so you don't get ink on it. Below you can see a few examples of shaker cards.
