Art Van Go and I always check out their stand when I visit major stitch shows.
Lastly to add a backing that adds some extra resilience to the fabric, in the form of iron-on light weight Vilene - I tend to use black as it's less visible when the fabric is used. Press on with an iron with a little steam - press from the back barely touching.
And so after no more than a couple of hours work, I have a new stock of metallic fabrics in a range of colours. I do promise you this product is quite resilient for both hand and machine stitching - although you need to stitch correctly first time to avoid unwanted stitch holes. Do have a go at making this very economical 'fabric' - I'd love to see photographs of projects it is used for.
