I don't really understand. Is it the base piece, a piece you want to use in the middle? Is it attached yet? I have a leaning one that I unfortunately didn't get quite straight.

It's a vase and actually it's the top part that's uneven but I want to use it upside down. Since the top part will be at the bottom and visible I wanted to even it out on the bottom part. I wish I could figure out how to import a picture so I could show you. Sorry I just seem to not be able to figure out how to do it.

If you find a way, this farmer may want to be clued in...LOL! just kiddin', flowers12, I see you got a pic of your beautiful glass vase in another post...the 'leaning' title made me think of this pic I took some yrs ago...a fav:

Good luck w/your project! Jeanne S.

I wish you could show a pic so I can see what you are trying to do.

One thing that helps me alot is, when I'm glueing more then one pc.I let each pc dry over night before I add another.
And when I'm doing a 2pcs. I let the glue dry for about 10 min. till the glue is really tacky, that way the pcs. don't have a chance to move around to much.
Hope that helps

I'm pretty sure I know what you're trying to do flowers. It sounds like your vase has a scalloped top edge or something similar. If it is an even pattern, as long as you get lots of silicone on the parts touching the piece below it, it should be fine. I've done a couple like that, then usually put a big line of silicone around the base of that particular vase, then put some glass globs or other decoration there to hide the excess silicone.

I hope that makes sense to you. If not, let me know and I will try and find a picture to show you.

Good luck and don't forget to let us see the finished product!
