My sister-in-law and I made a snowflake curtain for her grandmother's store. I used my Cricut to cut all of these out (but I think I'll remake one with my 4th grade class and have them cut out the snowflakes). It's such a super easy way to festive-up a window/wall/whatever.
The snowflakes were stitched together, but a little fishing wire and Scotch tape work wonders if you're not a sewer.
If you're going with a snowflake theme this Christmas, check out the Better Homes and Gardens Christmas craft section. This snowflake garland is the same idea and super adorable.
