I bought a length of black heavyweight fusible interfacing earlier in the year but I haven’t had much success with it fusing to anything. It’s also not what I would call heavyweight. I didn’t get any instructions with it (should have asked, I know), so it’s been trial and error each time I’ve used it. Sometimes steam works, sometimes not. Sometimes the iron needs to be hot, sometimes not. Sometimes I need to keep the iron in one place for a while, sometimes not. Sometimes it bonds to the fabric but mostly it just WON’T BOND AT ALL. You get the picture.
Yesterday I was in the mood to make mug rugs and thought the aforementioned interfacing would be ideal as a padding even if it didn’t bond to the felt I was using but this time it did, using steam. Perhaps it only likes to be associated with felt? Whatever.
4″ square of interfacing bonded to a 5″ square of felt on front and back but only free-machine embellished one side.
