These replies were just perfect, l knew some clever folk out there had the answers! I really appreciated hearing about real examples and how they've held up.
I have actually just finished the quilt (only my second ever, and the other was hand quilted). It's a combined DWR friendship star quilt of my own design, using fabrics from my stash and chosen by friends to celebrate a friend who is marrying and moving to the U.S. (I'm in the UK).
Predictably my friends didn't take my fabric guidelines to heart and one of them picked a lovely but very flimsy netting with spiderweb foil. I managed to incorporate a bit of it using interfacing to stabilise it, but l just couldn't work out how to quilt it without ruining the delicate look. Hence my question - thanks to you lot coming to my rescue l have now quilted little webby stars here and there in a colour that's almost invisible. Terrible photos attached, since curiosity was expressed! (It's just rough machine embroidery, no stabilisers)
