Here is a pumpkin bag for Halloween or fall. The layered svg file has four layers: one for scoring with solid lines, one for the bag, one for the face, and one for the stem. I cut the stem for my bag out of the same paper as the bag, and used markers to make it look like a stem. I used chalk on the front of the bag for more depth. You could use either a strip of paper or a ribbon for a handle if you wanted one.
The download includes a layered svg for use with SCAL 2.0, and two single layer svg files for use with SCAL 1.0. These files are for personal use only. Feel free to link to this post, but the files are not to be shared or distributed in any way.
