This is a vinyl sticker reading "If you call this a blanket," measuring approximately 2 1/2 by 2 1/2 inches. It is printed on premium vinyl with a matte finish and comes packaged in a clear bag. The line is a quilter's joke — one every quilter has heard from someone who does not know the difference.
The vinyl is both waterproof and weatherproof, which means it holds up outdoors and through washing rather than only resisting a spill. That suits a tumbler, a water bottle, a laptop, a planner or a journal, and the matte finish keeps it from throwing glare the way a gloss sticker does under overhead light. It is manufactured in the USA. Stickers like this tend to work as small gifts for a guild meeting or a class, where the joke lands with everyone in the room.
