I will try my best to put down the steps as I remember them for the #3 result.
#1. Create both text and design.
#2. Copy and paste both text and design so you have 2 of each.
#3. Create a box (from the shapes library) around 1 text, center both the box and text to the page and merge.
#4. Now center 1 design to the page (which should be centered over the text box) and pic front minus back, set that aside.
#5. Center the other text to the page, then center the other design to the page.
#6. pick front minus back.
#7. your design should fit in to the void in the text.
I hope I have explained this so it is understandable.
