Beautiful fabrics! And of course I must ask where you got them? You're very adventurous.
I think breaking needles is just a given with this kind of fabric. You can remove sequins from the seamline and allowances before stitching, and that will help, but I think you are just going to break needles with this kind of thing. With beads you can use a pliers or hammer (carefully) to break the beads in the SAs without unstitching them and loosening all the others, but I'm not sure that works with sequins, or that you'd like the results. I think you'd probably get a lot of little sharp sequin pieces poking you.
You can use any pattern you like for this kind of fabric. I'm not sure there's any particular style that's to be avoided at all costs or anything. There is a
good book by Susan Khalje about sewing wedding and evening gowns which of course covers the kind of fabric you're asking about. There's also lots of info in old Threads magazines if you have access to a collection. Your library may have them if you don't.
I'm sure you'll get lots more answers once everyone stops drooling over your gorgeous fabrics.

Hi Liana,
Even I, cannot stop drooling over them but the stigma, the stigma...I am starting to sweat just thinking about it!!! Every time I go thru all my stash away closet I'm just

to see the fabric again.
As for your question where i got the fabrics, could you believe i got it from a Lagos, Nigeria in a local market. Someone told me the fabrics came from either Dubai or India. It was then $15 per yard.I have no idea that time what I am getting into.
As for your suggestions about the Threads magazine i'll try to find some, since for now I'm based in Nigeria. But thanks for the info.
JUST for FYI i'll be posting lots of LOCAL Nigeria clothe from DA DIVA Collection. Here is there website
