fusible vs. heirlooms, long

If you are creating a quilt that you hope will hold its beauty a long time, you may want to consider this quote in QNM Oct 03. "...the chemical composition of the adhesives used in these quilting products generally is not identified nor has their long-term performance been evaluated...decisions about whether or not to use these products can not be informed by research at this time." (greatly snipped here and reading the whole article is worth your time). This brought to my mind the first time my mother used a bit of fusible, could have been 50 years ago. The dress was a sweet little rosebud sprinkled voile. The fusible in the facings turned a permanent and ugly yellow. Of course, fusibles have come a long way since then but it's impossible to forget how disappointed we were. How's that for today's little ray of sunshine? Polly
