read each package and choose the one that fits your needs best---they are not all the same- some are washable- some are not, some are made for wallhangings only; some are like the decal's on t-shirts, some are printed then ironed onto fabric....each has it's own instructions- ways to use it- so read and understand what you are buying. they tend to be fairly expensive-you don't want to buy one that turns out to not be best for your project-
