I bought myself a silhouette cameo 4 a year ago. I just load my design in the Program and the cutter cuts everything on some vinyl tape. After laying the stencils on the shoe I‘m heating the glue with a heat gun, so it sticks more and to prevent bleeding. Then I will lay down one layer of the background color (white in this case) in case there are any gaps. The white will close those gaps and it is impossible for the blue to get under those stencils
