My initial observations were that it's a bit like a looser, coarser version of Fast2Fuse - more pliable and slightly thicker. The glue is in globules rather than spread over the surface. It fused on nicely to my test piece of homespun cotton.
And then I rolled it and got a bit of a shock...
I'm used to Fast2Fuse doing this...
Ah... but then I realised I was rolling against the grain!! When it's rolled in the OTHER direction it does this......which is what Fast2Fuse does when you roll it against the grain. (In fact, I'm not sure which product this photo is actually of - Fast2Fuse on the wrong grain or Peltex on the right one - they really are VERY similar). This was a revelation to me - I hadn't realised that there actually WAS a grain in Fast2Fuse!!
A layer of medium-heavy interfacing between the fabric and the Peltex/Fast2Fuse softened the ripples on the surface, but didn't completley erase them on the Peltex.
(...oops! I can't spell PELTEX...)And THEN..... I tried a layer of light fusible wadding between the fabric and the stiff stuff.... and fell in love with Peltex.The surface of the fabric was softened by the wadding and the Peltex gave it stand-up support -without being as cardboard-box-like as Fast2Fuse can be (when you're sewing a bag that is completely interfaced with it).
I think the two products each have their pros and cons. (The most obvious balance is that Fast2Fuse is finer, smoother and more rigid than Peltex - and Peltex is half the price of Fast2Fuse).
I have to decide whether to stock it or not. I feel obliged to at least give it a go - having hassled that poor interfacing rep for the last four years...! I'd be really interested to hear your thoughts and experiences with Peltex - if you have any. Would you buy it, have you bought it, any hot tips for using it, does the price difference affect your purchase decision....? I'd love to know more about it from a user's point-of-view and any help is greatly appreciated!
