This product is a fun colorful set of 42 background designs (designed & created by me) that is made up of 6 designs in 7 different patterns (see preview). The background designs themselves are .png image files that you can manipulate to fit your creative needs. Use with your creative projects and products. OK to use for resale and profit on sites like Teachers Pay Teachers, etc. The file is a ZIP download. I have found the (free) unzipping software from PKWare to be the easiest to zip and unzip files. You can google "unzip reader by PKWare" to find and download it. Thanks for looking.
