hey Ad' you stated

"The seam in the middle normally get´s solved at th end of modelling.
When you combine the two halves, check for normals direction on both -flip the offending one if needed-, and finally Merge Vertices on the whole object with a 0,0001 tolerance.

If the middle edge isn´t that pronounced, then this should take care of it, if it still doesn´t suit you then you´ll have to tweak manually those middle vertices.

Hope this helps,"

Can I do this with subD objects? I cant seem to figure out how to do it! I have tried using poly-proxy mode as well as the normal mode. do you have a set work-flow process I could borrow?

Also... how do I deal with UV's after flipping and merging? I am really confused...

thanks man, you rock!

p.s. that animated gif of your flower modeling project was really cool. You know your stuff man!!
