In my search I discovered a very important tool, the weld option. At the bottom of the page there is a button next to what looks like a bulls eye that has a square and circle together. I saw that and I realized that was exactly what I needed to combine the circle and two ovals. It ended up being super easy. I saved the file with my master and then copied it and created new files with different sizes to make the garland, cupcake toppers, straw toppers, and hanging Mickey decorations.
I also used the Silhouette to make different size circles for the cups, the chip containers (this was a major score - I found these for $2 at Walmart in the garden section), and to make Jack's name.
Be sure to follow us as I am going to post a link to download the Mickey Chevron signs and Mickey Mouse thank you tags I used on the sugar cookies.
