My elementary school years were ruled by stickers. I had a couple of albums where I collected them, and I loved thumbing through the pages looking at the cute animals, sniffing the scratch-and-sniffs, and jiggling the pages the make the puffy googly eye ones google. Good times!
Both Society6 and Redbubble have my sticker designs. The Society6 versions are vinyl with either a white or transparent background. They offer four sizes ranging from 2 inches to 6 inches. All of my Society6 stickers are available here.
The Redbubble versions of my stickers are also vinyl and, like Society6, are available with a white or transparent background. With Redbubble, you have the option of a matte or glossy finish to the sticker. They are available in three sizes ranging from around 3 inches to around 7 inches. All of my Redbubble stickers are available here.
I have all of my designs on both sites, so it is just a matter of where you prefer to get your stickers.
And if you are not ready to commit to affixing stickers to your belongings, I have another solutions for you—magnets! My Redbubble magnets are made of flexible vinyl and are available in 3 inch, 4 inch, and 5 inch sizes. All of my magnets are available here.
