90-95% would be from purple+gold mats/decon items/research items that drop from crafting dailies, the other 5-10% is motifs or furnishing plans (It just depends on my rng for the week). Right now since mats are superhigh in value it's very easy to make a lot of gold from them.

Writs. Sell surplus gold and purple mats you get. Boring, boring, boring, but gold. I only do 4 chars per day but can do a lot more if I'm hungry for gold for some reason. Just doing 4 will usually get me 200-300K per week in gold mat sales.
