There are probably easier ways to make a rosette but this is how I make them.
Apologies for the horrid papers used but daughters bf is staying with us for a few weeks until his new flat is ready and as a consequence I'm having to share my playroom and all of my decent stash hidden away. (Took me over 8 hours to tidy it up yesterday, oops) Like most of the cardweight capable punches my SU border punches don't like thin nasty paper and I would have had a better result if I'd used something thicker than cheap loo paper ;o)
This is me teasing the folds into place, for once I've managed to hide how ink stained my fat lil puds are lol.
Next step is to cover the centre, I'm looking for a more traditional rosette look so I've used the 2nd largest large circle nestie (black) and the next size down (pink) which has been embossed with a bug folder but any size would have worked provided it was large enough to cover the edge where the 2 layers of rosette meet. Add a strong glue to the back and position on the rosette and press down quite firmly.
As you can see from the pic it's still trying to lift up in the middle. You can hold it down for a while if you want, I prefer to just plonk one of my heavier punches on top and clear off to make a cuppa lol. By the time the tea is made and drunk the rosette will be perfectly flat and ready to decorate or use as an embellie.
Not sure what I'm going to do with this whopper as it measures nearly 6" across but the lil one I made (on the first picture and made from a single inch strip) will no doubt end up on a card at some point.
