So, how to make it - the following pics are on orange cardstock so that it's hopefully easier to see how it's done. And, yes, I need to take some goo gone to the back of my dies to remove the washi tape residue. :)
This is how it looks when the die is removed. The arrows are pointing to the lines on either side of the flower.
Here's another view with the full oval shown.
Step 5. Run it through the die machine and remove the die and voilà! A partial die cut!
This is what it looks like once it's cut. Notice that the scissor cut goes to the drawn line which is lower than the die cut. That's okay - it's right next to the image so won't show when glued down. Carefully erase the pencil lines and continue on with your card. Isn't that fun? And, it's easy once you do one or two. :)
