Modge Podge makes a product just for FABRIC. You can get it at any craft store, like Michaels. Modge Podge has many products for different surfaces. So, make sure you've got the right bottle and that it's the one in matte. Just brush it over the letters, going right over the edges of the letters coming loose and it should be done! Modge Podge dries so quickly! GL
