What's the best way to organize your contacts in Jute Threads?

I'd love to hear how the rest of you all organize your contacts in Jute Threads. 

We work with a lot of contractors around the house so keeping them organized (and remembering what they did while they were here) can be a daunting task to say the least. 

I will usually make a Page with the contractor's contact information, and then make a Subpage each time they visit the house. On those subpages, I can detail out what work was done and can even invite the contractor to collaborate with me there via comments. 

At the end of the year, I can click on the contractor's name and view all of the subpages in one scroll, essentially mapping out everything that the contractor has done at the house in order and all in one place!

How do you all organize your contacts/threads?
