We make our own window decorations. We hand cut snowflakes and other seasonal items, or use our cricut. Then I laminate them (so they last longer and aren't affected by condensation in the winter) and we use double sided scotch brand poster tape to affix them to mirrors and windows. These snowflakes are in their third year on our windows now. Some of them are two layers of paper in blue and white. Nice dimension :) the kids love to hang them and make them!
