This adorable box and kitty were posted last year. (You can find the entire post, including a video HERE.) You can download the box HERE and the kitty HERE.
Or how about this one? (The entire post is HERE.) The box is two downloads HERE and HERE. The black cat can be downloaded HERE.
This box is super easy to put together. The tabs (where the glue will go) are solid yellow. You need to print both pages. If you have any questions, the video from THIS POST has a similar box.
Dropbox seems to work differently for different people. When the image appears, wait a moment and a download button will appear in the top right corner. If download button does not appear, right click on the image and save as. I'm always happy to email the image to you, if neither one works!
This card is super quick. Just print, cut , fold. You can download it HERE.
You can tell that I like plaid! Maybe one of these will work for you if you're looking for an easy quick-to-do Halloween goodie.
