I have a tip to share with you today: Don't throw away used envelopes without checking out the inside first! I have been collecting a few of their inside patterns and used them on this card. They form the background of the shaker windows, all of which are closed with a sheet of acetate attached to the back of the die cut shape.
If you fancy giving acetate a try yourself, you might want to check out challenge FTTC12 over at Flourishes.
The wool ribbon was a find at a flee market, the button is from a sewing shop, the wooden beads were in a children's crafting set, as were the butterflies.
