How to make my own beading strand for my dress?

I am getting my dress custom made and there is beading under the bustline on the "inspiration dress". My seamstress charges and extra $100 dollars to hand bead it or I can make/buy my own. It is basically a strand/ribbon of beads that will be sewn on. I have checked out michaels and found some things, but nothing I loved. Does anyone have any advice on where to find something like this or if I will need to by the beads and sew/glue them to the ribbon?

Here is the dress I am getting made, you can click on the view closer or altenative images to see the beading a bit better...

I would try an actual fabric store as opposed to a craft store like Michaels. They sell the appliques and stuff for dresses.

I would definitely sew it to the dress instead of gluing it. That way it will move with you in the dress.

You might see if you can buy the materials and have your seamstress sew it on if you aren't comfortable doing it.

I would just pay the extra $100 it is your bridal gown and god forbid you mess it up trying to add it with glue or you stitches come out...at this point what is $100 let the pro do it

The seamstress will attach it to the dress I just have to come up with the actually beading(on a ribbon). If she has to do a design and sew individual beads its $100.

Oh that is an entire different story then yes def try a fabric store...I know in NYC they have a lot of stores that soley sell trimming
