there are a number of fusables available- heat & bond lite, Steam a seam lite & wonder under are the 3 used most often-
you want to make sure you get the lite ones for projects that will be laundered- sewn down- the heavy products are made to not be sewn in & are more for art quilts-items that will not be laundered
you just need to ask for (paper backed fusable) not every store carries all 3- some shops have their favorite to carry. all 3 work fine- i use all 3---just read the instructions & follow them- each fusable product has it's own application process & you need to follow the one you are using for the best results.
