This buffalo check patterned background is quite unique in that it’s customizable in programs like Silhouette Studio or Cricut Design Space! It not only comes as a PNG file, but also as an SVG and DXF file so you can change the colors to the squares or lines as needed. So cool! Additionally, you can add a solid square behind the pattern to add an extra color. Try changing the opacity of the lines to create a different look as well. So many possibilities!
(Please ignore the weird little lines you may see in this image. It’s just how the screen is translating those diagonal lines. They aren’t really there.)
