I am going to share with you the technique I used to create the background in my Caboose Junction layout!
Here are the supplies I used...
I punched a circle (you can use any shape) into a piece of scrap cardstock. A background stamp and ink. I like to use the stamp in the circle because it gives me more control. It bothers me when I use a background stamp (like the one you see in the picture) and the edge of the stamp shows up on my layout! This technique eliminates that!
This is what it looks like after I have stamped using the circle as a stencil.
I added some mist, and my background is complete!
