Here is a picture of swing card designed on gypsy. Card size is standard 5 1/2 x 4 1/2 inches. Cartidge used for the basic card is George as my gypsy wanderings is messed up. Also this way it's easy to get out a cut file too. Note the inner snowman is not included as you can use any image at the center - maybe a turkey for thanksgiving. This card can be used for all occasions.

Both the cut file and gypsy file are available under respective names from the navigation bar at the top.
The first page is actual cut page. remember to keep the cricut speed low. there will be a small sliver of paper around the inner square - just snip it. The 2nd page is for cutting the middle square if you need it. I have used it for the red square and also can be used to size whatever images you want to place in the square at the back.. I have used the DCWV recycle green stack - 8 x 8 and the red paper was got separate from archivers from winter collection. The green and red embellishments are tiles and the bling in the center was also from archivers which I cut out from a bigger piece. The snowman was from snowfriends and I have used some glitter  for snow
Now for the the scoring and folding. Here's a picture
Do not score the inner square as it should be free to swing. Fold one side one way and the other - the other way :)  allowing the middle to swing free. If you are using single side paper you might want to cut page 2 - the inner square. Use this square also for sizing any image. It should not be bigger than this.
Once again the files for download are under gypsy and cut files in navbar.
