A great way to make your social media and blog uniform is to add the same design throughout. My first stop: Pinterest. Through photoshop I designed an image for each board and uploaded them to the board and set them as my cover image.
I found this great tutorial on Ladybug's Teacher Files. She used powerpoint to create the images, but you can make them in photoshop like I did.
Now my pinterest looks uniform and matches my blog theme.
I have already fixed up my facebook page.
Now on to my stores: etsy and TeachersPayTeachers.
Are there any other social media/stores that you will make uniform to your blog?
