Tips for blobing as France?

[D313.m]

I started playing EU4 a year ago and I can’t say I’m a pro but I’m neither a noob. The first Ironman game I played was with Milan so I had a difficult time forming Italy, and when I finally conquered the required provinces I faced the mega French-ottoman alliance. Now I’m playing with France and I’d like to know some tricks to grow bigger in Europe.

The summary of my current situation: (1550)
- All French culture group provinces owned but Liege, Avignon, and the HRE provine of Provence.
- Conquered East Anglia, Northumbria, Cumbria, Scotland, Ireland, Gaeldom as a vassal,
- PU over Castile, currently integrating them. I fed them with the coastal portuguese provinces and their colonies.
- I own Holland, all Catalonia, Savoie.
- Alliances: Bohemia and Ottomans, Bohemia (unfortunately) is the emperor after I gave him some austrian lands during wars.


I don’t want to attack Bohemia since they are a powerful ally. I’m planning to eat the last remnant of Provence during the league wars, hoping that Bohemia is to busy to honour the call of Arms...

ditch bohemia, disband the HRE, eat europe, at the same time when spain is done, start your conquest in north africa, vassals only for vassal feeding, you want to blob, then blob
nobody can stand against you already unless you wreck yourself with a worldwide coalition
