Re: Bidh for shaadi
you can get some of the material from Bulk Barn. and you can also check out karachi bazaar for either pre-made Biddh, or the packets of supari if you're assembling it yourself.
yup, i agree with SGC. you could also try going to any desi store, and finding individual packets of the things that you need. might be a little bit cheaper making your own, instead of buying pre-made ones.
if you're having trouble finding what to wrap them in, like femme mentioned, go to any crafts store (walmart's fabric section has lots of choice too) and pick out some material that you could use to make the pouches.
you would however, need a lot of man power if you decide on making them yourself. also depends on how many you wanna make :p
