You can easily get the iron on adhesive for your iron on badges from the embroidery store. Take your badge and set it face down upon an ironing board. Take the adhesive patch, peel one side of the paper and place it at the patch. Now take a sheet of clean cloth and put it over this sheet of adhesive. Put your iron on low or silk configuration and iron over this patch. Your patch has become ready to use. What you need to do is take away the backing sheet from your adhesive, secure it over the place you want it and then iron on the reverse.
