Combining objects into one cloth

[alexp]

I need to make the cushion attached.
I can get the "petals" scatter onto a cushion using Tyflow well enough, struggle a bit with having them uniformly spread out, but not a huge deal. Any tips there would be appreciated nonetheless.

But the main issue is how do I then get the entire thing to operate as one cloth object that I can then have collide and interact with a sofa for example. While maintaining each parts positioning in relation to each other just like it is stitched in reality?

Is this possible?

Any better ways to create such a thing?

Thanks!
