Once you have the basic shapes sized to fit your planner you can start adding decorations, text and list elements. Once you have them in place on top of the box shapes, change the colour of your pieces. Then use the flatten tool to take the individual pieces to turn them into printable pieces.
Make sure anything with a clear background has a shape put behind it.
Remember that the Cricut Print and Cut feature has a print area of 6.75 by 9.25 inches. Therefore, the best way to get the most out of your material is to create a template to work on. Take a square from the shapes library and resize it to 6.75x9.25 inches.
Then arrange your stickers into this template once you have everything in place, remove the square from the canvas, then select all of the images on the sheet and attach them together, this will keep them in place as you move to printing and cutting your material.
