WIP- Flower Failure

Here is a peak into a current work in progress.

It's supposed to bloom into a flower...

...with this pretty rivoli in the middle...

It fits but the beads are supposed to cup over the rivoli.

Otherwise, the rivoli pops out when pushed from the bottom.

I'm pretty sure I need to make the stitches a bit tighter. But I was yanking on them so hard that the string gave me a tiny cut... right on one of my knuckles (totally annoying). I want it to work so badly. It's discouraging but I can't give up!
