I frequently get asked where to order SQUARE sticker designs, and since Zazzle doesn't offer square stickers at this time, I have found some reasonably priced websites that do!
Shutterfly offers square stickers at a price of $5.99 for 24 stickers. They measure 1.75 x 1.75" in size.
Kodak Gallery offers Martha Stewart square stickers priced at $3.99 for 30. Each set of stickers is 2x2" square!
So now those favor tags and labels that I design, instead of only round, can also be designed as a square, for uploading to either of these 2 reasonably-priced websites!
Or course your regular monogram designs can also be turned in to stickers with these super-low prices!
Just thought I'd share!
