I saw an add about making patches using an inkjet printer on some type of fabric but lost the link and I can't recall the type of fabric. I've gone to michaels and they all look at me like I don't speak english. If it exists can someone let me know the brand name, and my second topic is these foam sleeping mats i'm seeing on some of the modern bashes. I have looked for an OD color foam material thin enough and can't find one anywhere. Again Michaels is of no help. Just curious what others have used.
