Here's my 2 cents worth...The old Steam a Seam products did have a shelf life but with care did ok for me.
Newer Steam a Seam, for me, has been too sticky even when following instr.s..Didn't like it !! Pellon = thumbs down !
Never have used Soft Fuse, but will try some soon. Didn't ever like Heat n Bond...but my LQS sells HnB Lite for
wool applique...and it does the job on wool ! A little stiff on other fabrics. I read some where...maybe here
...
about a new product from Heat n Bond....HeatnBond Feather Lite . LQS gave me a sample they got at Market
and I have had great results with it. Big Bernie...normally fussy...has handled it ok...and it is supple and so far
stayed put ! Of course...none have that 2 sided quality of SS2.
But I will try new things as they come along.
